UNIT 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 209. 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.3. A block is being pulled up a ramp as shown in the diagram below. Assume that the ramp is frictionless. FT = 150N 15.0 kg 350 a. Draw the force diagram for the block on the ramp. b. What is the x-component of the force of gravity acting on the block on the ramp? c. Calculate the acceleration of the block. 4. Repeat problem 3, except now, assume that the frictional force acting on the block on the ramp is 25.0 N
