On a frictionless air track where motion is constricted to a line, a 2.0-kg glider moving in the positive x-direction at 4 m/s collides elastically with a 3.0-kg glider moving in the negative x-direction at 6 m/s. What are the velocities of both masses after the collision?
You place a 3.0-m -long board symmetrically across a 0.5-m -wide chair to seat three physics students at a party at your house. If 70-kg D sits on the left end of the board and 50-kg T on the right end of the board, where should 54-kg K sit to keep the board stable? Ignore the mass of the board and treat each student point- like objects. The positive z-direction is to the right, and the origin is at the center of the chair.

- Two metersticks are connected at their ends as shown in Figure P10.18. The center of mass of each individual meterstick is at its midpoint, and the mass of each meterstick is m. a. Where is the center of mass of the two-stick system as depicted in the figure, with the origin located at the intersection of the sticks? b. Can the two-stick system be balanced on the end of your finger so that it remains lying flat in front of you in the orientation shown? Why or why not? FIGURE P10.18 (a) The center of mass of the stick on the x axis would be at (0.5 m, 0), and the center of mass of the stick on the stick on the y axis be at (0, 0.5 m), assuming the sticks are uniform. We can then use Equation 10.3 to find the x and y coordinates of the center of mass. xCM=1Mj=1nmjxj=12m[m(0.50m)]=0.25myCM=1Mj=1nmjyj=12m[m(0.50m)]=0.25m The location of the center of mass is (0.25m,0.25m) (b) No. The location of the center of mass is not located on the object, so your finger would not be in contact with the object. In a different orientation, balancing by applying a force at the center of mass might be possible, but not in the orientation shown.arrow_forwardA girl of mass mg is standing on a plank of mass mp. Both are originally at rest on a frozen lake that constitutes a frictionless, flat surface. The girl begins to walk along the plank at a constant velocity vgp to the right relative to the plank. (The subscript gp denotes the girl relative to plank.) (a) What is the velocity vpi of the plank relative to the surface of the ice? (b) What is the girls velocity vgi relative to the ice surface?arrow_forwardFigure P9.59a shows an overhead view of the configuration of two pucks of mass In on frictionless ice. The pucks are tied together with a string of length 1' and negligible mass. At time t = 0, a constant force of magnitude F begins to pull to the right on the center point of the string. At time t, the moving pucks strike each other and stick together. At this time, the force has moved through a distance 4 and the pucks have attained a speed v (Fig. P9.59b). (a) What is v in terms of F, d, e, and in? (b) How much of the energy transferred into the system by work done by the force has been transformed to internal energy?arrow_forward

- intro to physics, thank you! You set up a 20 cm tall ramp on a 75 cm tall table. The ramp is inclined at 30° to the horizontal.You place a 500 g block at the end of the ramp, and release a 750 g block from rest at the topof the ramp. The ramp exerts 1.6 N of friction on the block. The two blocks are equippedwith velcro so they stick together after colliding. The ramp is designed so the objects travelhorizontally off the table immediately after colliding.(a) How fast are the two blocks traveling just after the collision?(b) How far from the table do they land?arrow_forwardA rod 2 meters long has a linear density of p(x) = 8 - 3x. How far, in meters, is the center of mass of the rod if measured from the left?arrow_forwardTwo cars of equal mass approach an intersection. Car A is moving east at a speed of 45 m/s. Car B is moving south at a speed of 35 m/s. They collide inelastically and stick together after the collision, moving as one object. Which of the following statements is true about the center-of-mass velocity of this system? a. The center-of-mass velocity will decrease after the collision as a result of lost energy (but not drop to zero). b. The center-of-mass velocity will remain the same after the collision since momentum is conserved. c. The center-of-mass velocity will drop to zero since the two objects stick together. d. The magnitude of the center-of-mass velocity will remain the same, but the direction of the velocity will change.arrow_forward
