A 12.0 kg box slides from rest down a frictionless ramp with an angle of 30 with horizontal. After the box has traveled 10.0 m, how much work was done by the normal force? O 59 J O OJ O 118 J O 102 JA block is travelling with an initial velocity of 50 m/s along a horizontal frictionless surface when it encounters a frictionless ramp at 30 with horizontal. Determine the distance that the block slides along the ramp. 222 m 512 m 128 m 256 m 0000 A forklift raises a 200kg crate through a vertical distance of 2.70 m.
