1. What is the weight of a car sitting on a 14˚ slope if the force required to push the car up the hill is 750 pounds?
2. A 3,000‐pound car is sitting on a 12˚ slope. Find the magnitude of the force required to keep the car from rolling down
the hill and the magnitude of the force perpendicular to the hill.
3. Two people push a 200‐pound box up a ramp. Each person pushes with a force of 75 pounds in the direction of the
incline up the ramp, and the box just slides along the ramp. At what angle is the ramp inclined?
4. Determine the work done by a crane lifting a 2400‐pound car 5 feet.
5. A force of 50 pounds, exerted at an angle of 25˚ with the horizontal, is required to slide a desk across the floor.
Determine the work done in sliding the desk 15 feet.
6. A force of 600 pounds is required to pull a shipping crate up a ramp inclined at 25˚ from the horizontal. Find the
weight of the shipping crate
