This is work and power, can someone please show me how to compute this?  A 5.1 x 102 kg prize-winning pumpkin is raised from the ground to a truck platform, a distance of 1.1 m, by several volunteers. The action takes 3.2 seconds. Calculate:  a) the work required to raise the pumpkin b) the power of the lift

. A box with a mass of 3.00 kg is pushed a distance of 2.0 m by a horizontal force of 12.0 N across a frictionless table. Determine the work done by: a) the applied force b) the normal force c) the force of gravity d) the net force on the block

Needs Complete typed solution with 100 % accuracy.

A 65.0-kg file cabinet of is sliding down a rough ramp for a distance of 5.00 m as shown. The friction force on the box is 75.0 N. During this process, what is the work done on the cabinet by the friction 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 50-N crate initially has kinetic energy 10.0 J at the top of a rough incline of 60 degrees.   A constant horizontal force is applied to the crate as it moves down the incline in dynamic equilibrium.    Is the work from the following forces positive, negative or zero?   Explain your reasoning. Normal, Weight, Applied and Friction Is the net work positive, negative or zero?  Explain your reasoning. How do your answers for (a) and (b) change if the crate is displace up the incline instead?
