2. (T) Ms. Fizics pushed a large crate of textbooks (75 kg) down the hall to her office. She pushed as hard as she could and the crate accelerated down the hall at a rate of 1.5 m/s2. There was a coefficient of kinetic friction of 0.48 between the crate and the floor. (a Draw a free-body diagram for the crate. [2] (b) Determine the net force on the crate. [2] (c) Determine the crate's normal force. [2] (d) Determine the force of friction on the crate. [2] (e) Determine the force exerted by Ms. Fizics. [2] 3. A 55 kg skier starts at rest at the top of a 32 m high hill. a. How much kinetic energy does she have at the bottom of the hill? b. How fast is she moving? c. Another student has a mass of 85 kg. How fast is he moving at the bottom of the hill
