A 250 g cart is travelling at 15 m/s to the right. It collides inelastically with another cart travelling to the left at 10 m/s. After collision the carts are travelling to the left at 2 m/s. What is the mass of the second cart

Object A has a mass of 50kg and is moving along the +x axis with a speed of 10m/s. Object B has a mass of 65kg, and is moving at 8m/s in the positive y direction.  The two objects collide at the origin and stick together.  What is their final velocity?

Two hockey players traveling at 12 m/s (Player #1) and 19 m/s (Player #2) hit in a head-on collision. They grab onto each (face to face) in other to keep from falling and slide in the same direction Player #2 was traveling at a speed of 5 m/s.  Player #1 has a mass of 100 kg.  What is Player #2’s mass?

A 1500 kg aircraft going 35 m/s collides with a 2000 kg aircraft that is parked and they stick together after the collision and are going 15 m/s after the collision. If they skid for 123.9 m before stopping, how long (in seconds) did they skid?

A fast car is speeding down a road with a velocity of v. It collides with a truck moving in the opposite direction that has a mass that is four times that of the fast car. They are both moving at the same speed. If the collision is elastic, then what are both of the vehicles velocities given as multiples of v.

A 55.0 kg boy runs at a speed of 16.0m/s and jumps onto a cart that is initially at rest. The boy and the cart then move off together at a speed of 2.50m/s. What is the mass of the cart?

A car of mass 2000 kg traveling east at 20 m/s strikes a 3500 kg truck traveling west at 10m/s. The car and truck lock bumpers and stick together. What are the final speeds of the car and the truck ?

A 1,120-kg car traveling initially with a speed of 25.0 m/s in an easterly direction crashes into the rear end of a 9,100-kg truck moving in the same direction at 20.0 m/s (see figure below). The velocity of the car right after the collision is 18.0 m/s to the east. +25.0 m/s +18.0 m/s +20.0 m/s After Q (a) What is the velocity of the truck right after the collision? (Round your answer to at least three decimal places.) x m/s (east) Before (b) How much mechanical energy is lost in the collision? x) Account for this loss in energy

A 14,000-kg boxcar is coasting at 1.50 m/s along a horizontal track when it suddenly hits and couples with a stationary 10,000-kg boxcar. What is the speed of the cars just after the collision? m/s
