Question

Please solve 1D and 2 DEF.

1. A 20.0 kg box is pulled up an inclined ramp by a rope with tension of 150.0 N. The incline makes an angle of 30.0 above the horizontal. The rope is parallel to the ramp. There is a kinetic friction force of 30.0 N a. Draw a free body diagram of the box, listing all forces acting on the box. b. Find the work done by each force on the box. c. Find the net work on the box. d. If the box starts from rest, what is the speed of the box after traveling 4.50m up the ramp? 2. A person with mass mo drops from a diving platform into the pool ho meters below. a. What is the diver's gravitational potential energy when standing atop the platform? b. How much kinetic energy does the diver possess at impact? Vc. What is the diver's velocity vo at impact? d. What about a diver with mass m,-2mo? - what will their velocity v, be at impact? e, what if the diver with mass mo dives from a platform hr=2ho meters-what will their velocity v be at impact? What height h2, is necessary for the diver with mass mo to attain a velocity of 2v% f.
