36. ao Object A is moving due east, while object B is moving due north. They collide and stick together in a completely inelastic collision. Momentum is conserved. Object A has a mass of m, = 17.0 kg and an initial velocity of Vm = 8.00 m/s, due east. Object B, however, has a mass of mg = 29.0 kg and an initial velocity of Vo = 5.00 m/s, due north. Find the magnitude and direction of the total momentum of the two-object system after the collision.

A west bound 1500 kg car moving at 13.0 m/s collide with a north bound 2500 kg car moving at 20.0 m/s. Ifthe cars stick together after collision, calculate the magnitude and direction of their common velocity.

A 1500 kg car traveling eastwards at 25 m / s collides with a 2500 kg load truck going north at a speed of 20 m / s as shown in the figure. Find out the magnitude and direction of the speed of the wreck after the collision, taking into account that the vehicles had a completely inelastic collision.

A ball of mass .62 kg has an initial velocity of 7 m/s and moves at an angle of 32° above the +x-direction.

Two blocks, m1 = 1.50 kg and m2 = 3.00 kg, are traveling to the right along africtionless surface. Block m1, moving 4.00 m/s, catches up to block m2, moving 2.50 m/s, and the two blocks undergo an elastic collision.(a) Determine the velocity of each block after the collision. (b) Prove that the collision was, in fact, elastic.

he figure shows an approximate plot of force magnitude F versus time t during the collision of a 56 g Superball with a wall. The initial elocity of the ball is 35 m/s perpendicular to the wall, in the negative direction of an x axis. It rebounds directly back with pproximately the same speed, also perpendicular to the wall. What is Fmax, the maximum magnitude of the force on the ball from the all during the collision?
