Name:    Physics -- Momentum Word Problems                   (Mom = Mass (x) Velocity) (Note:  The problems may look familiar, but the numbers are different!)

(Note:  Print this test out on your printer.  Use the included solution boxes to work out your answer.
When you have the answers, come back to the web page and input your answers using the guidelines
listed below.  This test accepts answers in the format of
Mom = 3 kg-m/sec     (or)     Mom=3kg-m/sec
--- in other words, your answers must either have a space after the missing variable, a space after the
equals mark, and a space after the number OR no spaces!)

This question has 3 parts:

a. A 2 kg red toy car begins at the right side of a long table and rolls across a table top to the middle at 1.5 cm/sec.  What is itís MOMENTUM?

b. From the left side of the table a 0.5 kg. blue toy car rolls towards the middle at 3 cm/sec.  What is itís MOMENTUM?

c. When these two toy cars collide, consider these questions:
1. Which one has MORE momentum, the red one or the blue one?

2. How MUCH MORE momentum does it have?

3. After the collision in which DIRECTION will the cars roll?  Why?
