A factory worker pushes a 30.0 kg crate a distance of 4.5 m along a level floor at constant velocityby pushing horizontally on it. The coefficient of kine

A crate of mass 23 kg is pushed up a ramp by a person as shown in the figure below. The person pushes the crate a distance of 27 m as measured along the ramp. Assume the crate moves at constant velocity. Assume the coefficient of kinetic friction between the crate and the ramp is 𝜇K = 0.32. angle is 30 degrees What is the work done by the person as he pushes the crate up the ramp?

A man pushes an 80-N crate a distance of 5.0 m upward along a frictionless slope that makes an angle of 30° with the horizontal. His force is parallel to the slope. If the speed of the crate decreases at a rate of 1.5 m/s2, then the work done by the man is:

A worker pushing a 35.0 kg wooden crate at a constant speed for 12.0 m along a woodfloor does 350 J of work by applying a constant horizontal force of magnitudeF on the crate.(a) Determine the value of F.(b) If the worker now applies a force greater than F, describe the subsequent motion ofthe crate.(c) Describe what would happen to the crate if the applied force is less than F.

4. A crate is pulled up a ramp a distance of 20 m with a force of F = [800, 500]. The crate ends up 2 m higher above the ground than where it started.

4. A crate is pulled up a ramp a distance of 20 m with a force of F = [800, 500]. The crate ends up 2 m higher above the ground than where it started. a. (APP - 4 marks) Find the force applied on the crate that moves the crate up the ramp and the force that is perpendicular to the ramp that lifts the crate up off the ramp. b. (APP - 2 marks) Find the work done moving the crate up the ramp and the work done lifting the crate 2 m above the ground.
