Unit 4: Momentum and Collisions

Problem Set B

 

Problem 13:

A 1.5-kg cannon is mounted on top of a 2.0-kg cart and loaded with a 52.7 gram ball. The cannon, cart, and ball are moving forward with a speed of 1.27 m/s. The cannon is ignited and launches a 52.7 gram ball forward with a speed of 75 m/s. Determine the post-explosion velocity of the cannon and cart. Enter a negative value for a backward velocity and a positive value for an forward velocity.
