A 10-g bullet moving horizontally strikes and passes through a 4.0-kg block moving with a speed of 4.2 m/s in the opposite direction on a horizontal, frictionless surface. If the block is brought to rest by the collision, and the bullet emerges with a speed of 320m/s, what is the initial speed of the bullet?

Use the worked example above to help you solve this problem. Two billiard balls of identical mass move toward each other as shown in the figure. Assume that the collision between them is perfectly elastic. If the initial velocities of the balls are v1i= +25.2 cm/s and v2i = −20.3 cm/s, what are the velocities of the balls after the collision? Assume friction and rotation are unimportant. (Indicate the direction with the sign of your answer.)

Find the magnitude and direction of the velocity of the wreckage after the collision, assuming that the vehicles undergo a perfectly inelastic collision (that is, they stick together) and assuming that friction between the vehicles and the road can be neglected.
Initially, ball 1 rests on an incline of height h, and ball 2 rests on an incline of height h/2 as shown in the figure below. They are released from rest simultaneously and collide elastically in the trough of the track. If m2 = 6m1, m1 = 0.048 kg, and h = 0.38 m, what is the velocity of each ball after the collision? (Assume the balls slide but do not roll. Indicate the direction with the sign of your answer. Positive is to the right, and negative is to the left. Due to the nature of this problem, do not use rounded intermediate values in your calculations—including answers submitted in WebAssign.) v1f = m/s v2f = m/s

Mechanic Physics: Please make sure this is right #10 In the figure, block 1 of mass m1 slides from rest along a frictionless ramp from height h = 3.4 m and then collides with stationary block 2, which has mass m2 = 2m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction μk is 0.15 and comes to a stop in distance d within that region. What is the value of distance d if the collision is (a) elastic and (b) completely inelastic?
