Question

Two blocks can collide in a one-dimensional collision. The block on the left hass a mass of 0.30 kg and is initially moving to the right at 2.4 m/s toward a second block of mass 0.80 kg that is initially at rest. When the blocks collide, a cocked spring releases 1.2 J of energy into the system. (For velocities, use to mean to the right, – to mean to the left).A) What is the velocity of the first block after the collision?
B) What is the velocity of the second block after the collision?

a) 3.632 m/s

b) 0.462 m/s

Explanation:

Using the law of conservation of momentum:

……….(1)

Substituting the above values into equation (1) and make V2 the subject of the formula:

………………(2)

Using the law of conservation of kinetic energy:

…….(3)

Substitute equation (2) into equation (3)

Substituting into equation(2)
