The Canadians are at it again with this strange game called curling (except this time with a twist). This time you slide your stone A which weighs 50 lbs with a velocity of 4 ft/s. Stone B is somewhat deformed and only has a mass of 45 lbs and is initially at rest. The coefficient of restitution between the stones is 0.8. Find the velocities of stone A and B after the collision and express it in terms of a Cartesian coordinate vector.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
