III: Worksheet 3 1. A 20 kg mass is allowed to accelerate down a frictionless 15 ramp. 20 kg 15 a. Draw a force diagram for the block. b. Determine the value of the x-component of the force of gravity. c. Calculate the acceleration of the block. d. Calculate how long will it take for the block to slide 30.0m. 2. An applied 25 N force pushes on a 5.0 kg block resting on a frictionless horizontal surface. The force is directed downwards at an angle of 20. 20 a. Draw a force diagram for the block. b. Determine the x-component of the applied force. c. Calculate the acceleration of the block. d. Calculate the normal force on the block.
