Physics

1. A toy car of mass 2.0 kg moving to the right with a speed of8.0 m/s collides perfectly inelastically with another toy car ofmass 3.0 kg that is moving to the left with a speed of 2.0 m/s.Find the magnitude and the direction of the velocity of the systemImmediately after the collision.

2. In an elastic collision of two objects,

a. momentum is not conserved.

b. momentum is conserved, and the kinetic energy after thecollision is less than its value before the collision.

c. momentum is conserved, and the kinetic energy after thecollision is the same as the kinetic energy before thecollision

d. the kinetic energy of the system after the collision dependson the masses of the objects

3. Object 1 has more kinetic energy than Object 2. How do themagnitudes of their momenta compare?

a. P1=P2

b. P1>P2

c. p1 ≥ p2

d. not enough information given to tell
