A young girl is riding a bicycle that has a total mass (including the kid) of 21.2 kg. The girl is moving at 5.99 m/s on a flat road when suddenly she slams on the brakes and skids to a stop in 8.22 meters. What was the magnitutde of the average force due to friction acting on the bicycle? Remeber, the magnitude of a force is always positive. Assume a constant friction force measured in Newtons and 3 significant digits in your answer.
A doctor is testing how much impact force does a 75 kg athlete has on his knees when he jumps. On his first jump, he landed with stiffed legs, and it took 0.4 m/s for him to stop.
