A ski starts from rest and slides down a 22deg incline 75 m, Ask an Expert

Academics

Q. A ski starts from rest and slides down a 22° incline 75 m long. If the coefficient of friction is 0.09, what is the ski's speed at the base of the incline? If there is snow level at foot of the incline and it has the same coefficient of friction, how far would the ski travel along the level?

Q. A 33kg crate rests on a horizontal floor, and a 73kg person is standing on the crate. Find out the magnitude of the normal force that floor exerts on the crate. Also determine the magnitude of the normal force that crate exerts on the person.
