Two boxes collide – box A of mass 3.0 kg, and box B of mass 5.5 kg. Box A is initially moving to the right at 3.2 m/s, while box B is initially at rest. After the collision, box A is moving to the right at 0.65 m/s. 22. After the collision, box B will be moving at a speed of from which we can calculate that the collision was ii The statement above is best completed by the answers in row: Row i ii 1.39 m/s inelastic

I need to calculate initial and final momentum for 2 runs and then the change in momentum.  the mass of the object is .3 kg  initial velocity of run 1 is -.5 m/s and final velocity is .13 m/s initial velocity of run 2 is -.4 m/s and final velocity is .8 m/s   please show/explain how to solve for this

As shown on the right two identical objects have the same mass. They are moving with the same speed but one is going due North and the other is going due East. Which of the following statements is completely correct? North a. East m m V Select one: They both have the same kinetic energies and the same momentum. b. They have different kinetic energies and they have different momentum. OC. They have the same kinetic energies, but they have different momentum. Od. They have different kinetic energies, but they have the same momentum.

A 70.0 kg ice hockey goalie, originally at rest, has a 0.280 kg hockey puck slapped at him at a velocity of 45.5 m/s. Suppose the goalie and the puck have an elastic collision, and the puck is reflected back in the direction from which it came. What would the final velocities ?goalie and ?puck of the goalie and the puck, respectively, be in this case? Assume that the collision is completely elastic.

Two ice skaters (Abe and Bob) stand at rest in the center of an ice rink. When they push off against one another, Abe (45 kg) acquires a final speed of 0.62 m/s. If Bob's final speed is 0.88 m/s, a.) What is Bob's mass? kg b.) For the Abe+Bob system, please find: before they push on each other: momentum: kg-m/s kinetic energy: J after they finish pushing off each other: momentum: kg-m/s kinetic energy:

Summarize what happens to momentum and kinetic energy in an inelastic collision. That is, compare and contrast the momentum and kinetic energy before and after an inelastic collision.

Two balls of the same mass are thrown towards a wall and collide with it moving with a speed of 5 m/s.  Ball A hits the wall and rebounds with a speed of 4 m/s.  Ball B hits the wall and stops.  How does the velocity change, momentum change and impulse of Ball A compare to that of the Ball B?   1)  Each ball has the same velocity change, momentum change and impulse.   2)  Ball A has the greater velocity change, momentum change and impulse.   3)  Ball B has the greater velocity change, momentum change and impulse.   4)  Ball A has the greater velocity change and momentum change; the impulses are the same.   5)  Ball A has the greater velocity change; the momentum change and the impulses are the same.

A mass ma = 2kg slides down slippery ramp, reaching a speed v = 10 m/s at the bottom. After reaching the level ground ma collides with mass mg = perfectly inelastic collision. 3kg at bottom, sticking together in a a.) What was the height of the ramp, assuming that m, started from rest? b.) How fast were the combined masses ma and mg moving after sticking together? c.) The combined mass runs into a spring, which brings it to a stop after being compressed 7 cm. What is the spring constant k ?

1D Elastic Collision 1. You have two balls. They will collide elastically in 1D. Choose the following: • The masses of the balls (they cannot have the same mass). • The initial velocities of the balls (neither can be at rest).  Solve for the final velocities of the balls after the collision using Conservation of Momentum and Conservation of Energy  • Solve, you must draw a picture, set photo 1 and photo 2, and draw origin and axes?
