If the final velocity of the can of Coke is 5.63 m/s still toward the right, then what is the final velocity of the can of Pepsi? Assume the two cans have equal masses. 6.

If she throws the wrench with speed 16 m/s, then what will be her recoil speed? 7. A. 0.6883 m/s D. 0.6200 m/s 0.4844 m/s E. 0.5996 m/s 0.5968 m/s F. 0.4480 m/s ARC ABC 1--1

A ball is thrown vertically up, reaches a maximum height, and then falls back down to the ground. Which of these is true during the flight of the ball? O a. The momentum of the ball stays constant O b. The speed of the ball changes at a constant rate O c. The momentum of the ball changes at a constant rate O d. The acceleration of the ball changes at a constant rate

The impulse - momentum theorem states that the impulse on an object is equal to:A. The change in its velocityB. The change in its accelerationC. The change in its momentum D. The change in its kinetic energy
