Determine the initial momentum p¡, final momentum pf, and change in momentum Ap of a 1250-kg car initially backing up at 6.00 m/s, then moving forward at 15.0 m/s. Define forward as the positive direction. P₁ = Ap= kg-m/s kg-m/s Pf= kg-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

Item 9 A0.30 kg billiard ball traveling at a speed of 13 m/s strikes the side rail of a pool table at an angle of 60°.(Figure 1) Part A If the ball rebounds at the same speed and angle, what is the magnitude of the the change in its momentum? Express your answer using two significant figures. ΠνΟ ΑΣφ Др- kg - m/s Submit Previous Answers Request Answer Figure 1 of 1 > X Incorrect; Try Again; 8 attempts remaining Part B What is the direction of the the change in its momentum? O right O upward O left O downward
