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.

A 90kg man walks on a sawhorse, as shown below. The sawhorse is 2.0m long and 1.0m high, and its mass is 25.0kg . Calculate the normal reaction force on each leg at the contact point with the floor when the man is 0.5m from the far end of the sawforce. (Hint: At each end, find the total reaction forces first. This reaction force is the vector sum of two reaction forces, each acting along one leg. The normal reaction force at the contact point with the floor is the normal (with respect to the floor) component of this force.)
