Question

Ian is firmly attached to a snowboard which is on a flat surface of ice, which you can assume to be frictionless. He and the snowboard are initally at rest. He then throws a 144.0g ball which travels at a speed of 18.4 m/s, and finds himself moving backwards at a speed of 0.05 m/s. What is the combined mass of Ian and his snowboard (in kg)?

Explanation / Answer

by the conservation of momentum i.e.

initial momentum = final momentum

0 + 0 = (0.144)(18.4) - (0.05)(M) where M is the combined mass od Ian and snowboard.

M = 52.99 Kg ........>>>> ANSWER
