On Oct 31 2015, massive asteroid TB145 nicknamed "Spooky" passed near the Earth
vicinity. The measured diameter of the asteroid: 600meters, and its speed relative to
the Sun: 30.5 km/s.
(NOTE you are not given the parameters of collision, so they become important part
of the "worst case -best case scenario.") Treat the asteroid as spherical object with
the density of between 3g/cm³ to 4g/cm³. Treat an Earth's orbit around the Sun as a
perfect circle of radius =150 x 106 km. Take one year to be 365.24days.
Find the worst case scenario for the collision of such object with the Earth and find
the Maximum energy released in the completely inelastic collision of this object with
Earth. State your answers to the nearest mega-ton of TNT. (1 megaton of TNT=
4.184 X1015J).

For years, the tallest tower in the United States was the Phoenix Shot Tower in Baltimore, Maryland. The shot tower was used from 1828 to1892 to make lead shot for pistols and rifles and molded shot for cannons and other instruments of warfare. Molten lead was dropped from the top of the 82.15 m tall tower into a vat of water. During its free fall, the lead would form a perfectly spherical droplet and solidify. Determine the velocity of the droplet right before it hits the ground. (Note: acceleration = -9.81 m/s/s) (Hint: think about the direction the droplet travels when considering its displacement.)

In a dark matter direct detection experiment, a dark matter particle is supposed to directly
interact with the atoms in the detector, causing either a nucleus or an electron to recoil
after the collision has occurred. The dark matter particles in our galaxy should be moving at
non-relativistic speeds, so this scattering process can be described using the conservation of
momentum governed by Newton's laws without the need for quantum mechanics. One of
the most common target materials for these experiments is xenon. Your goal is to answer
the following question.
Assuming there is a dark matter particle with incident velocity v1 that will scatter from a
Xe-136 nucleus (with a mass of 136 amu) that was initially at rest as shown below. What is
the dark matter mass?
You should solve for the answer symbolically first. Then you will substitute in the values
shown below to get out an actual numerical value for the mass, in amu.

- You have been hired as an expert witness in an investiga- tion of a quadcopter drone incident. The incident occurred during a very rare meteor shower during which several unusually massive chunks of meteoric material were passing through the atmosphere and striking the ground. The unmanned drone was hovering at rest over the center of a house on fire, having just dropped fire retardant, when it seemed to spontaneously explode into four large pieces. The locations of the four pieces on the ground were meas- ured as follows, relative to the center of the house over which the drone was hovering: Distance from Center Direction Piece # Mass (kg) of House (m) from House 1 80.0 150 Due west 2 120 75.0 Due north 50.0 90.0 20.0° west of south 4 150 50.0 20.0° north of east The fire department is suggesting that the drone was defec- tive and exploded while in use. The drone manufacturer is suggesting that the drone was struck by a meteorite, causing the explosion.

A bullet of very small mass m = 20 g (m << M) is fired at a high speed v. = 120 m/s towards the first block. It quickly exits the first block at a reduced speed of 0.40 v, then strikes the second block, quickly getting embedded inside of it. All the motion happens on the x-axis. (a) find the speeds of the two blocks after their encounters with the bullet. (b) Now the first block catches up with the second one and collides with it. They got stuck together afterward and move forward. Find their common speed V after the collision. (c) The two blocks now hit a light spring of spring constant k = 35 N/m mounted on the wall. How far is the spring compressed before the blocks reach a momentary stop?arrow_forwardAn asteroid of mass m = 500 kg is moving through space at velocity Vmi = 3i+2j-9k(ms^-1).

The alpha particle slows until it momentarily stops when its center is at radial distance r from the nuclear center. Then it moves back along its incoming path. (Because the gold nucleus is much more massive than the alpha particle, we can assume the gold nucleus does not move.) What was the kinetic energy K; of the alpha particle when it was initially far away (hence external to the gold atom)? Assume that the only force acting between the alpha particle and the gold nucleus is the (electrostatic) Coulomb force and treat each as a single charged particle. 9.23 fm It was actually experiments like this, performed between 1908 and 1913 by Hans Geiger and Ernest Marsden, under the direction of Ernest Rutherford at the Physical Laborato- ries of…arrow_forwardA 0.25 kg mass of clay is moving with a horizontal velocity of v when it collides and sticks to a 5 kg object hanging from the end of a 1 meter long rod.

- A projectile with a mass m = 200 kg and a velocity v = 100 ms-¹ is fired at an angle of = 60°. At the highest point of its trajectory, it explodes and breaks into three pieces with the same mass.

One of those two pieces moves vertically downwards, and the other moves horizontally forward. a) Compute the velocity of the third piece right after the explosion. b) What was the released energy of the explosion?arrow_forwardThe Moon’s craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 4.95 × 1012 kg (such an asteroid is about a kilometer across) strikes the Moon at a speed of 14.5 km/s relative to the Moon. What is the change in kinetic energy, in joules, in the collision?

Suppose that the orbital velocity of each star v = 220 km / s and the periodic time of each one 14.4 days find the mass M for each star (compared to the sun’s mass, M= 1.99 x 10^30 kg).

At this very instant, the x and y components (Ux, U,) of the mice's velocities are, respectively, (U₁x, U₁₁y) = (0.591 m/s, -0.425 m/s,) (v2.x, U2,y) = (-0.605 m/s, -0.933 m/s,) (v3,x, U3,y) = (0.259 m/s, 0.305 m/s), and (V4x, V4,y) = (-0.211 m/s, 0.569 m/s). Calculate the x and y components px and py of Bryce's mice's total momentum. Px = kg.m/s Py = kg.m/sarrow_forward
