Consider a different scenario in which the carts stick together after the collision. The masses of the heavier and lighter cart are and , respectively. Derive an expression for the fraction of kinetic energy lost during the collision. Express your answer in terms of and .

The slotted link is pinned at o, and as a result of rotation it drives the peg p along the horizontal guide. compute the magnitude of the velocity and acceleration of p along the horizontal guide. compute the magnitudes of the velocity and acceleration of p as a function of θ if θ=(3t) rad, where t is measured in seconds.

What do you think car designers do if the damage caused by a crash test is too severe?

Aball of mass 0.3kg is released from rest at a height of 8m.how fast is it going when it hits the ground? accleration due to gravity is g=9.8m/s
