Question
Impulse-Momentum
A 3.0-kg block slides on a frictionless horizontal surface, first moving to the left at 50 m/s. It collides with a spring as it moves left, compresses the spring, and is brought to rest momentarily. The block continues to be accelerated to the right by the force of the compressed spring. Finally, the block moves to the right at 40 m/s. The block remains in contact with the spring for 020s. What were the magnitude and direction of the impulse of the spring on the block? What was the springs average force on the block?
