Unit 4: Momentum and Collisions
Problem Set B
A small 24.1 gram fish moving with a speed of 36.9 cm/s is engulfed by a large fish which is initially at rest and has 3 times the mass of the little fish. Determine the post-lunch speed (in cm/s) of the big fish (with the small fish in its stomach).
General nformation about solving collision problems is described on the Set B Overview page.
A detailed description of the use of momentum conservation and proportional reasoning as a guide to thinking about collision problems is provided online at The Physics Classroom.
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.
