A car with a mass of 1850kg is traveling east with a speed of 8.5m/s. It collides head-on with a car with a mass of 2050kg traveling west with a speed of 5.5m/s. The cars stick together after the collision. What is the velocity (magnitude and direction) of the two cars after the collision

A 0.250 kg toy car moving with a speed of 0.820 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

A student is driving a 1200 kg car at 42.0 m/s. He is tail-gating ("drafting") behind a 2500 kg truck that is going 40.0 m/s in the same direction as the car. (DON'T EVER DO THIS! IT IS EXTREMELY DANGEROUS AND ILLEGAL) The car collides with the truck and the two vehicles are stuck together. How fast are they moving after the collision?

A 92 kg boulder , moving at 5.0 m/s attempts to pass directly across the adit of a mine. Just as the boulder reaches the end of the adit, it was met head-on in midair by two 75 kg miners, both moving in the direction opposite the boulder. One is moving 2.0 m/s, the other at 3.0 m/s . They all become entangled as one mass. What is their velocity after the collision? 18. What is the momentum of a 18 kg object traveling at a constant velocity that has 295 J of kinetic energy?

A 0.250 kg toy car moving with a speed of 0.820 m/s collides with a wall. The figure shows the force exerted on the car by the wall over the course of the collision. What is the magnitude of the velocity, or final speed, of the car after the collision?

A toy car having mass m = 1.20 kg collides inelastically with a toy train of mass M = 3.95 kg. Before the collision, the toy train is moving in the positive x-direction with a velocity of Vi = 2.10 m/s and the toy car is also moving in the positive x-direction with a velocity of vi = 4.95 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. (a) Determine Vf, the final velocity of the toy train.   (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.

A car, with a mass of 1240 kg, is moving towards an intersection at a velocity of 26.6 m/s towards the South. At the intersection, it collides with a truck that has a mass of 1580 kg and is moving with a velocity of 14.0 m/s towards the West. When they collide, the two vehicles stick together. 15. The magnitude of the final velocity for the car and truck is Answer to 3 significant digits. m/s. (Record your answer in the numerical-response section below.) Your answer:

A 2.51 kg ball of clay is traveling straight north with a speed of 24.0 m/s, collides with a 3.55 kg ball of clay traveling straight east with a speed of 22.1 m/s. What is the speed of this new ball of clay after its collision? What direction is it traveling, given as a degree north of east?

Blocks A and B are moving toward each other on a horizontal, frictionless surface. Block A has a mass of 5 kg and a velocity of +40 m/s, while B has a mass of 10 kg and a velocity of -6 m/s. They suffer a head on, completely inelastic collision. What is the common speed of the blocks after the collision.

A 10.5-g bullet is fired into a stationary block of wood having mass m = 5.01 kg. The bullet imbeds into the block. The speed of the bullet-plus-wood combination immediately after the collision is 0.602 m/s. What was the original speed of the bullet? (Express your answer with four significant figures.)
