1) A 200 N block is pushed up a frictionless, 30°, 3 m inclined plane by a force F parallel to the inclined plane. The specd of the block at the bottom of the inclined plane is 0.5 m/s and 4 m/s at the top. Draw F the free body diagram and find; 30° a) The work done by the force F and the magnitude of the force F, b) If the frictional coefficient between the block and the inclined plane surface is 0.15, the speed of the block at the top of the inclined plane under the same force.
