Concept #1: Impulse & Impulse-Momentum Theorem

Practice: You throw a 100-g ball with 30 m/s. If the ball is in your hand for 0.2 s, find the impulse you deliver to it. 

EXTRA: Calculate the average force that you exert on the ball.

Example #1: Intro to Impulse

Example #2: Momentum & Impulse

Practice: You catch a 624-g basketball originally moving with 10 m/s. Calculate the impulse delivered to the ball.

Practice: When a 300-g ball is dropped from 3 m, it hits the floor and rebounds to a height of 2 m. If the ball is in contact with the floor for 0.02 s, what is the average force exerted by the floor on the ball?

Practice: A box of unknown mass on a flat surface slows down from 12 m/s to 4 m/s after crossing a rough patch. The box-patch coefficient of friction is 0.5. Use impulse/momentum to find how long (in s) the box takes to cover the entire patch.
