Two carts of identical mass m are on a track moving in one dimension.  Cart 1 is motionless and Cart 2 is moving at 5.0 m/s to the left.  Cart 2 collides with Cart 1. After the collision, Cart 1 is moving at 4.0 m/s to the left.  What is the velocity of Cart 2? (Assume elastic collision neglect friction between the carts and the track).

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 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

Two shuffleboard disks of equal mass, one orange and the other green, are involved in a perfectly elastic glancing collision. The green disk is initially at rest and is struck by the orange disk moving initially to the right at vi = 4.40 m/s as in Figure a, shown below. After the collision, the orange disk moves in a direction that makes an angle of 8 = 40.0° with the horizontal axis while the green disk makes an angle of = 50.0° with this axis as in Figure b. Determine the speed of each disk after the collision. of=1 m/s m/s Vgf= Before the collision After the collision. b of Ⓡ

Two otters are sliding toward each other on a muddy frictionless horizontal surface. One of them, of mass 7.5 kg, is sliding to the left at 5.0 m/s, and the other, of mass 5.75 kg, is moving to the right at 6.00 m/s. They hold fast to each other after they collide. What is the magnitude of the velocity of these otters right after they collide? O 0.116m/s 0.236m/s O 0.441m/s O 0.226m/s

Two toy cars with masses of 0.70 kg  and 0.30 kg, respectively, move towards each other and collide  head-on and then stick together.. The magnitude of the initial velocity for each of of the toy cars is 15.0 m/s. What is the speed of the toy cars  immediately after collision?

A 83.8-kg boy and a 59.4-kg girl, both wearing skates face each other at rest on a skating rink. The boy pushes the girl, sending her to the left with a velocity of -2.72 m/s. Neglecting friction, determine the subsequent velocity of the boy to the right. Answer: + m/s

Two gliders with mA = 0.50 kg, mB = 0.40 kg, collide elastically on a frictionless surface. Glider A with a spring bumper initially moves to the right with the speed of 4.0 m/s and glider B with a spring bumper initially moves to the left with the speed of 7.0 m/s. What is the final velocity of the glider A after collision?

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 85.4-kg boy and a 61.3-kg girl, both wearing skates face each other at rest on a skating rink. The boy pushes the girl, sending her to the left with a velocity of -2.52 m/s. Neglecting friction, determine the subsequent velocity of the boy to the right. Answer: + m/s
