1. The problem statement, all variables and given/known data How much work is done by the horizontal force Fp = 150 N on the 18 kg block of the figure when the force pushes the block 2.1 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? m/s 2. Relevant equations [Hint: Work-energy involves net work done.] http://www.webassign.net/gianpse4/7-29.gif 3. The attempt at a solution I know the answer to (c) is zero and I know how to do the problem when the force is parallel to the incline, but I am not sure how the values change with the force being at an angle.
