I've got 2 problems:

Number 1: Greg is pushing a 32 kg crate across the floor. He is making like difficult by applying his 800 N force down at an angle of 37 degrees below the horizontal. The coefficient of kinetic friction between the crate and the floor is .50.

I need to find the normal force, and the acceleration.

Number 2: After completing her jump, a ski jumper is going back up a hill on the other side, which is designed to slow her down. The hill is angled at 37 degrees to the horizontal. The coefficient of kinetic friction between her bargain basement skis and the snow is .20. Her mass, including all equipment, is 80kg

I need the normal force, the force of friction, and her acceleration
