A truck is moving at 15m/s when the brakes are applied, in order to come to a stop before hitting a pothole 20m ahead. In the back of the truck is a crate. It is not tied down, but has a coefficient of static friction μs = 0.4 with the truck bed. Will the truck be able to stop in time, without the crate sliding? 4) What equation must be true if the crate doesn’t slide, and false if it does? 5) Draw a free body diagram for the crate. 6) Construct the Newton’s Second Law equation for the crate, and solve for the magnitude of the static friction force.

5) Draw a free body diagram for the crate.
6) Construct the Newton’s Second Law equation for the crate, and solve for the magnitude of the static friction force.
7) Compute the maximum static friction force, and compare to your value from #6.
