A car with a mass of 980 kg is initially traveling east toward an intersection with a speed of vc = 20.2 m/s and a 1500 kg pickup is traveling north toward the same intersection. The car and truck collide at the intersection and stick together. After the collision, the wreckage (car and truck) moves off in a direction of 40.0° above the x-axis. Determine the initial speed of the truck and the final speed of the wreckage in meters per second.

A toy car having mass m = 1.20 kg collides inelastically with a toy train of mass M = 3.90 kg. Before the collision, the toy train is moving in the positive x-direction with a velocity of Vi = 2.30 m/s and the toy car is also moving in the positive x-direction with a velocity of vi = 4.90 m/s. Immediately after the collision, the toy car is observed moving in the positive x-direction with a velocity of 2.05 m/s. (a) Determine Vf, the final velocity of the toy train.m/s(b) Determine the change ΔKE in the total kinetic energy. Assume friction and the rotation of the wheels are not important so that they do not affect ΔKE. J Question 6.1b:A block with mass M = 5.50 kg is sliding in the positive x-direction at Vi = 8.85 m/s on a frictionless surface when it collides elastically in one dimension with a stationary block with mass m = 1.30 kg. Determine the velocities, Vf and vf, of the objects after the collision. Vf = m/s vf = m/s

A large block of mass 3.80 kg slides on a frictionless table and collides head-on with a small block of mass 2.50 kg. After the collision both blocks move in the same direction as the original motion of the large block, and fall off the edge of the table. The small block hits the floor at a point 2.18 meters horizontally from the edge of the table, while the large block hits the floor at a point 1.38 meters horizontally from the edge of the table. The top of the table is 1.10 m above the floor. Find the speed, in m/s, of the large block before the collision.

A toy car having mass m = 1.50 kg collides inelastically with a toy train of mass M = 3.60 kg. Before the collision, the toy train is moving in the positive x-direction with a velocity of Vi = 2.35 m/s and the toy car is also moving in the positive x-direction with a velocity of vi = 4.60 m/s. Immediately after the collision, the toy car is observed moving in the positive x-direction with a velocity of 1.90 m/s.       Determine the change ΔKE in the total kinetic energy. Assume friction and the rotation of the wheels are not important so that they do not affect ΔKE.           ------ joules
