The employee pulis a grocery cart loaded with items across the aisle for 12000.0 millimeters. The employee exerts a horizontal force of 110.0 N and the floor exerts a frictional force of 43.0 N as well. What is the net work done on the cart? 804 Joules 1,830 Joulos 1,320 Joules 516 Joules

To push a 3-kg crate up a frictionless incline angled at 20° to the horizontal, a worker exerts a force of 120 N parallel to the incline. The crate moves a distance of 8 m, (useg = 10 m/s²). What work is done on the crate by the worker? Submit Answer Tries 0/3 What work is done on the crate by gravity? Submit Answer Tries 0/3 What is the work done on the crate due to the normal force of the inclined plane surface? Submit Answer Tries 0/3 What is the net work done on the crate? Submit Answer Tries 0/3 If the crate begins at rest, what is the final speed of the crate as it is moved from the bottom to the top of the inclined plane? m/s

A student could either pull or push, at an angle of 30⁰⁰ from the horizontal, a 60 kgkg crate on a horizontal surface, where the coefficient of kinetic friction between the crate and surface is 0.21. The crate is to be moved a horizontal distance of 25 mm A) Compared with pushing, pulling requires the student to do more, less, or the same work. B) Calculate the minimum work required for both pulling and pushing. Express your answers using two significant figures separated by a comma. Answer must be in J Wpulling, Wpushing =

8. A boy pulls a 22.0-kg box with a 110-N force at 38° above a horizontal surface. If the coefficient of kinetic friction between the box and the horizontal surface is 0.19 and the box is pulled a distance of 30.0 m, what is the net work done on the box?

A worker pushing a 35.0-kg wooden crate at a constant speed for 13.6 m along a wood floor does 400 J of work by applying a constant horizontal force of magnitude F0 on the crate. (a) Determine the value of F0. ____N (b) If the worker now applies a force greater than F0, describe the subsequent motion of the crate. (c) Describe what would happen to the crate if the applied force is less than F0.

An owner tries to move their sleepy dog by pulling him across the floor. The dog slides across the floor for 0.50m at a constant speed while his owner puts a force of 107.5N at an angle of 700 on him. The dog weighs 147N and a 37N friction force acts between him and the floor. The Free Body Diagram is provided.  In the table, calculate the work done by each of the forces in sliding the dog.  fill in chart
