(a) How much work is done by the horizontal force Fp = 150 N on the 1S-kg block of 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? (e) 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 .

Hi! great video. for finding the angle for the normal force why are you using mg pointing downward instead of Fn pointing upward if we are looking for the work done by normal force?

How do you calculate the work of the friction force, assuming the coefficient of friction = 0, 10
