Unit 4: Momentum and Collisions

Problem Set B

 

Problem 6:

A 72.7 kg fullback moving eastward with a speed of 5.4 m/s collides head on with a 105-kg lineman moving westward with a speed of 7.6 m/s. Determine the post-collision velocity of the two players (assuming they grab each other and move together as a single object). Enter a negative value for a westward velocity and a positive value for an eastward velocity. 

 

 

 

 

 

 

 

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.
