Cart X (m = 4.0 kg) is traveling to the right at 3.50 m/s toward Cart Y. Cart Y (m 9.0 kg) is traveling to the left at 1.5 m/s. (p= m x v) %3D %D 3. Which cart has the larger magnitude of momentum, and why? А. Cart X has the larger magnitude of momentum because it has a larger magnitude of velocity. В. Cart X has the larger magnitude of momentum because it has the larger product of mass and velocity. Cart Y has the larger magnitude of momentum because it has a larger mass. D. Cart Y has the larger magnitude of momentum because it has the larger product of mass and velocity. С.

A 1200-kg car moving at 15.6 m/s suddenly collides with a stationary car of mass 1500 kg. If the two vehicles lock together, what is their combined velocity immediately after the collision? O6.9 m/s 8.6 m/s O 12.1 m/s 5.5 m/s

A 0.53 kg toy car bounces against a wall as shown below. Take right to be positive and left to be negative so WATCH YOUR SIGNS!!! Сазе А Yi=5 m/s =4 m/s Case B Yi=5 m/s Y,=0 m/s In case A, what is the initial momentum of the car? kg*m/s In case A, what is the final momentum of the car? kg*m/s In case A, what is the change of momentum of the car? kg*m/s In case A, what is the impulse experienced by the car? kg*m/s In case B, what is the change of momentum of the car? kg*m/s Compare cases A and B and then generalize. In which case is there a bigger change of momentum: when an object bounces or when it sticks? O it is the same in both cases there is not enough information to answer the question when it bounces when it sticks

D 2. A 250-g ball moving in the positive direction at 18 m/s strikes a wall and bounces off at 14 m/s in the opposite direction. The magnitude of the change in the ball's momentum is 32 Ns 16 Ns 8 Ns 4 Ns
