**Unit 4: Momentum and
Collisions**

**Problem Set B**

**Problem 1: **

A 2013 kg pick-up truck moving with a velocity of 22.76 m/s collides with a 896 kg car which is at rest at a stoplight. What is the magnitude of the velocity (in m/s) of these two vehicles after the collision (assuming they stick together and move as a single object)?

- Read the problem carefully and diagram the physical situation (collision diagram)
- Identify known and unknown information in an organized manner (list on diagram)
- Take the time to plot out a strategy prior to beginning the solution
- Identify an appropriate formula to use (or use a momentum table)
- Perform step-by-step algebraic manipulations

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.
