After pushing a 22.2 kg kid and tricycle over 10.3 m of smooth, level sidewalk from rest, the "combo" is moving at 3.0 m/s. Find the combo's kinetic energy. (the answer is 99.9j) what net force must have been delivered to the combo?Now you stop pushing and let the combo coast to a stop. The only force stopping the combo is the force of friction. If the force of friction is 7.9 N, how far will the combo coast before it stops?
