(Enter your answers in joules.) (a) the horizontal force (b) the frictional force (c) the net work (d) what is the change in kinetic energy of the box?

Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 18.0 N.  How much work is done on the box by the tension force, in Joule? Use g = 10.0 m/s2. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A 2.0-kg particle moving along the x-axis is acted upon by the force that varies with position as shown below. The speed of the particle at x = 0 is v = 6.0 m/s. Find the work done by the force from x = 0 to x = 4.0 m, and particle’s speed at x = 4.0 m.

Starting from rest, a 4.3-kg block slides 2.40 m down a rough 30.0° incline. The coefficient of kinetic friction between the block and the incline is p, = 0.436. (a) Determine the work done by the force of gravity. (b) Determine the work done by the friction force between block and incline. (c) Determine the work done by the normal force. (d) Qualitatively, how would the answers change if a shorter ramp at steeper angle were used to span the same vertical height?

Mr. Mangan pushes a 90 kg box across a rough surface with a force of 350 N over a displacement of 8 m. The coefficient of kinetic friction between the box and the surface is 0.3. Find the work done by Mr. Mangan, by friction, and the net work.

A 90.0 N box of papayas is pulled 10.0 m along a level surface by a rope. If the rope makes an angle of 20.0° with he surface, and the force in the rope is 75.0 N, how much work is done on the box?

An Athlete pulls a 30 kilograms crate along Lane A of the storage house. Lane A is a 15m  aisle. Using the yellow rope, he exerted an 55N force 15 degrees above the horizontal.   Q: -How much work is done by the athlete? -If the crate moves at constant velocity and the 55N force is enough to overcome friction , what is the net work done by all the forces acting on the box? Explain pls

Rachael is pulling a 47 kg box up a hill with a 40 degree angle above the horizontal at a constant velocity. The coefficient of kinetic friction between the floor and the box is 0.23. What is the work done on the box by the tension if the box moves up 2.1 m.

A 7.00-kg package slides 2.50 m down a long ramp that is inclined at 24.0  below the horizontal. The coefficient of kinetic friction between the package and the ramp is μk = 0.370. Calculate the work done on the package by friction. Calculate the work done on the package by gravity. Calculate the work done on the package by the normal force. Calculate the total work done on the package. If the package has a speed of 2.40 m/s at the top of the ramp, what is its speed after it has slid 2.50 m down the ramp?
