A 1.2 kg coconut is traveling east at 1.1 m/s when it suddenly explodes into two pieces. A 0.2 kg fragment is shot due north at 1.6 m/s. What is the speed of the second fragment?

A stationary firecracker explodes into two pieces. The piece shot to the right has a mass of 0.07 kg and is traveling 45 m/s. How fast is the smaller 0.04 kg piece, which travels to the left? Ignore friction and air resistance.

A 0.33-kg bullet traveling at 495 m / s strikes a 2.5-kg block of wood at rest, passes through it, and exits the opposite side at 273 m / s. What is the speed of the block when the bullet leaves it?

A 0.17-kg red billiard ball moving at 1.6 m/s strikes a blue billiard ball of the same mass moving in the opposite direction at 0.50 m/s. The blue billiard ball rebounds and travels at 0.80 m/s after the head-on collision. What is the final velocity of the red billiard ball after collision? 0.15 m/s 0.30 m/s 0.42 m/s 0.06 m/s

1. A 0.0850-kg bullet is fired at a stationary tin can whose mass is 0.215 kg. The bullet passes through the can, exiting the back of the can with a speed of 22.5 m/s. If the speed of the bullet is 99.0 m/s before it hits the can, what is the speed of the can after the collision?

A 40,000kg object moving to the right at 3.1m/s collides with a car of mass 55,000kg moving to the left at 520cm/s. The two cars couples together. What is their speed after the collision? (A) 1.7m/s to the left (B) 3.8m/s to the left (C) 1.7m/s to the right (D)5.9m/s to the right (F)3.8m/s to the right

A basketball (m = 0.60 kg) is dropped from rest. Just before striking the floor, the ball has a momentum whose magnitude is 3.7 kg.m/s. At what height was the basketball dropped? IN

A 0.032 kg bullet strikes a 4.8 kg stationary piece of lumber and embeds itself in the wood. The piece of lumber and bullet fly off together at 7.2 m/s. What was the original speed of the bullet?

This amazing summer adventure is finally winding down with some pool. Unfortunately, this pool table is wonky and some of the balls are larger than the others! Anthony hits the cue ball (mass = 0.15 kg) and it moves at 5 m/s when it strikes head on into the number 3 ball (mass = 0.30 kg). After this inelastic collision, the cue ball moves off at 60 degrees relative to the +x axis and the number 3 ball moves off at -30 degrees relative to the +axis as shown. What were the speeds of the two balls after the collision?
