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.]
2- A 46.0-kg crate, starting from rest, is pulled across a floor
with a constant horizontal force of 225 N. For the first 11.0 m the
floor is frictionless, and for the next 10.0 m the coefficient of
friction is 0.20. What is the final speed of the crate after being
pulled these 21.0 m?
explain them clearly ..
