A 4.6 kg mess kit sliding on a frictionless surface explodes into two 2.3 kg parts, one moving at 4.3 m/s, due north, and the other at 5.0 m/s, 32° north of east. What is the original speed of the mess kit?

A 7.17 g pellet is shot horizontally from a BB gun at a speed of 24.8 m/s into a 28.7 g wooden block. The wooden block is attached to a spring and lies on a frictionless table. If the collision is inelastic and the spring constant k = 16.0 N/m, what is the maximum compression of the spring?

Problem 5: A 1.8 kg falcon catches a 0.65 kg dove from behind in midair. What is the speed of the pair of birds right after the catch if the falcon's initial speed was 28 m/s, the dove's initial speed was 7 m/s, and they were moving in the same direction?

A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jumps from the first log onto a second. After landing safely on the second log, she slows down and ends up standing on the second log. Both logs both have masses of 150 kg each and the mass of the lumberjack is 70 kg. The lumberjack reaches a speed of 7.0 m/s relative to the shore during her jump. What is the speed of the lumberjack after she has stopped on the second log? You may assume the drag of the water on the logs is very small. Please answer in units of m/s.

A railroad car of mass 3.20 x 10* kg moving at 3.35 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s. (a) What is the speed of the three coupled cars after the collision? m/s (b) How much kinetic energy is lost in the collision? Need Help? Read It

Two asteroids of equal mass collide in an ellastic collision. Asteroid A has an initial velocity of 40 m/s. After the collision, asteroid A deflects an an angle of 30° above its initial direction. Asteroid B is initially at rest. After the collision, asteroid B travels at 45° below the original direction of asteroid A. What are the final speeds of the two asteroids?

A lumberjack is standing on a log floating on a lake. She starts from rest, then runs along the log to the end, when she jumps from the first log onto a second. After landing safely on the second log, she slows down and ends up standing on the second log. Both logs both have masses of 150 kg each and the mass of the lumberjack is 70 kg. The lumberjack reaches a speed of 7.0 m/s relative to the shore during her jump. What are the speeds of the two logs and of the lumberjack after she has stopped on the second log? You may assume the drag of the water on the logs is very small.

A 2.8 kg block of wood sits on a frictionless table. A 3.0 g bullet, fired horizontally at a speed of 510 m/s , goes completely through the block, emerging at a speed of 210 m/s . What is the speed of the block immediately after the bullet exits?

an archer shoots an arrow toward a 0.3 Kg target that is sliding in her direction at a speed of 2.50 m/s on a smooth, slippery surface. The 0.0225 Kg arrow is shot with a speed of 35.0 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target?

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?
