Problem A.1: Interstellar Mission
You are on an interstellar mission from the Earth to the 8.7 light-years distant star Sirius. Your spaceship can travel with 70% the speed of light and has a cylindrical shape with a diameter of 6 m at the front surface and a length of 25 m. You have to cross the interstellar medium with an approximated density of 1 hydrogen atom/m3.
(a) Calculate the time it takes your spaceship to reach Sirius.(b) Determine the mass of interstellar gas that collides with your spaceship during the mission.
Note: Use 1.673 × 10−27 kg as proton mass.
Problem A.2: Time Dilation
Because you are moving with an enormous speed, your mission from the previous problem A.1 will be influenced by the effects of time dilation described by special relativity: Your spaceship launches in June 2020 and returns back to Earth directly after arriving at Sirius.
(a) How many years will have passed from your perspective?(b) At which Earth date (year and month) will you…
Could you explain what happened to the left hand side of the equation? I understand that if l is not equal n then the second term of right hand side is zero, but i don't understand what happened to the sum to the left.
Assuming a one-dimensional collision, apply the conservation of energy theorem to the following system:In the system in the initial state, cart A is launched at the speed (vi ± delta vi) towards cart B, which is stationary.In the final state system, the two carts stick together and move together.The masses of the carts are known, as well as their uncertainty.Obtain a model for vf (the final speed of the carts) and its uncertainty based on known parameters only.
Consider a collision between cart A, moving at speed (vi ± delta vi), and cart B, immobile. The masses of the carts are known, as well as their uncertainty. Friction is neglected.
Using the conservation of energy theorem, program cells to predict the speed of sliders A and B after the collision as well as its uncertainty.
Then test your model with the following values:
mA=(0.47±0.05) kg
mB=(0.47±0.06) kg
vi A=(1.9±0.02) m/s
