Practice Impulse in Physics

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

The product of force and time interval, equal to the resulting change in an object's momentum.

A big push for a short time or a small push for a long time can have the same effect.

Example 1

easy
A force of 200 \text{ N} acts on a ball for 0.05 \text{ s}. What is the impulse delivered to the ball?

Example 2

medium
A 0.15 \text{ kg} baseball moving at 40 \text{ m/s} is hit by a bat and reverses direction at 50 \text{ m/s}. What impulse did the bat deliver?

Example 3

medium
A 60 \text{ kg} person jumps and lands on the ground, changing velocity from -4 \text{ m/s} (downward) to 0 \text{ m/s} in 0.5 \text{ s}. What average force does the ground exert?

Example 4

medium
A 0.20 \text{ kg} hockey puck moves at 3 \text{ m/s} east, then is struck and moves at 7 \text{ m/s} west. What impulse was delivered to the puck?
