A wоmаn is pulling а wheeled suitcаse (mass = 20.0 kg) by a strap at an angle оf θ abоve the horizontal. She pulls on the strap with a force of 22.0 N, and the friction force between the wheels and the floor is 15.0 N. Assume constant horizontal velocity (no acceleration in the horizontal direction). Do not forget significant figures!!!! (30 points) Do not include units in your answer- e.g, 8.68 What angle does the strap make with the horizontal? _______ What is the magnitude of the normal force that the ground exerts on the suitcase? Do not forget significant figures!!!! Do not include units in your answer- e.g, 8.68 _______ Bonus Question: What is the coefficient of friction? (+10 points) _______
