1- How much work is done by the horizontal force Fp = 150N on the 18-kg block when the force pushes the block 5.0 m up along the 32° frictionless incline? (b) How much work is done by the gravitational force on the block during this displacement? (c) How much work is done by the normal force? (d) What is the speed of the block (assume that it is zero initially) after this displacement? [Hint: Work-energy involves net work done.]...
