Determine how many rocks must she throw per minute

Reference no: EM13674478

A child sits in a wagon with a pile of 0.70 kilogram rocks. If she can throw each rock with a speed of 10 m/s relative to the ground, causing the wagon to move, determine how many rocks must she throw per minute to maintain a constant average speed against a 4.0 Newton force of friction?
