After pushing a 22.0 kg kid and tricycle over 11.0 m of smooth, level sidewalk from rest, the "combo" is moving at 4.4 m/s.
a) Find the combo's kinetic energy.
b) And, what net force must have been delivered to the combo?
c) 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 6.3 N, how far will the combo coast before it stops?
