Unit 4: Momentum and Collisions

Problem Set B

 

Problem 9:

A 1.27 kg cannon is at rest. When ignited, it fires a 51.3 g tennis ball forward with a speed of 48.2 m/s. Determine the post-explosion speed (in m/s) of the cannon. (Be careful of units!) 

 

 

 

 

 

 

 

General nformation about solving collision problems is described on the Set B Overview page.

A detailed description of the momentum conservation principle is provided online at The Physics Classroom.

Detailed solutions and discussions of several sample momentum problems are provided online at The Physics Classroom.
