Document Summary
Write your answers in the blanks provided. (8 pts) 1. A small rock is thrown from the roof of the building with a speed of 20. 0 rn/s at an angle of 37 above the horizontal. The rock strikes the ground 3. 5 s after it is thrown. A block with mass 20. 0 kg rests on a ramp that is inclined at 53 above the horizontal. A light rope passes over a light frictionless pulley and connects the 20. 0 kg block to a 6. 0 kg block that hangs vertically in the air. N: what is the coefficient of kinetic friction /1k between the block and the surface of the ramp? (12 pts) 4. A small rock with mass 0. 20 kg slides without friction inside a horizontal steel pipe that has inside radius r = 0. 80 rn. A block with mass 0. 40 kg is attached to a horizontal spring that has force con stant 500 n/ni.
