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.]...

(3 points) A9.8 kg crate is pulled 5 m up a 30 degree incline by a rope angled 16 degrees above the incline. The tension in the rope is 135 N and the crate's coefficient of kinetic friction on the incline is 0.22. How much work is done by the tension? J. How much work is done by gravity? J. How much work is done by the normal force? J. What is the increase in thermal energy of the crate...
7. (20 pts) A force of 50 N is used to move a 5 kg box 30 m across a level floor. a. How much work was done on the box? b. If the movement takes 10 seconds, what is the average velocity of the box during the move? c. What is the average kinetic energy of the box during the move? d. What is the change in potential energy as a result of this move?
A factory worker pushes a crate of mass 32.0 kg a distance of 4.20 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and floor is 0.25. What magnitude of force must the worker apply? Express your answer using two significant figures. F = N Part B How much work is done on the crate by this force? Express your answer using two significant figures. W = J ...
