Mass m = 0.1 kg moves to the right with speed v = 0.54 m/s and collides with an equal mass initially at rest. After this inelastic collision the system retains a fraction = 0.9 of its original kinetic energy. If the masses remain in contact for 0.01 secs while colliding, what is the average force in N between the masses during the collision? Hints: All motion is in 1D. Ignore friction between the masses and the horizontal surface. You...
