In a football game, two players collide and bounce apart. The player coming from the left, Player A, is moving at +2 m/s. The player coming from the right, Player B, is moving at -3 m/s. After they collide, Player A is now moving at -3 m/s and Player B is now moving at +2 m/s. What statement best answers what we know about their mass? Answer choices: A. The mass of Player A must be smaller than Player B B. The mass of Player B must be smaller than Player A. C. The mass of Player A must equal the mass of Player B. D. We do not have enough information to exactly calculate their masses.
5. A rocket standing on its launch platform. points straight upward. Its jet engines are activated and eject gas at a rate of 1500 kg/s. The molecûles are expelled with a speed of 50 km/s. How much mass can the rocket initially have if it is slowly to rise because of the thrust of the engines?

云 HI 5 F. %24 -10 Part A Jeanette is playing in a 9-ball pool tournament. She will win if she sinks the 9-ball from the final rack, so she needs to line up her shot precisely. Both the cue ball and the 9-ball have mass m, and the cue ball is hit at an initial speed of v. Jeanette carefully hits the cue ball into the 9-ball off center, so that when the balls collide, they move away from each other at the same angle 0 from the direction in which the cue ball was originally traveling (see figure). Furthermore, after the collision, the cue ball moves away at speed vf, while the 9-ball moves at speed vp. (Figure 1) Find the angle 0 that the 9-ball travels away from the horizontal, as shown in the figure. Express your answer in degrees to three significant figures. > View Available Hint(s) For the purposes of this problem, assume that the collision is perfectly elastic, neglect friction, and ignore the spinning of the balls.

2. A cart of mass 300 g moving along a straight track hits a 500 g cart which had been sitting still. After the carts hit, the 300 g cart has a speed of 1.0 m/s back to where it came from, while the 500 g cart is moving forward at 3.0 m/s in the same direction as the 300 g cart had been going at the beginning. How fast was the 300 g cart going before it hit the 500 g cart?
