very confusing :(

i have a big assingment due april 7th , i have answered all the questions but 4 are left. can anyone help me... pleaseee :D

1. Terry uses a force of 10.0 N to push her CD player a distance of 0.50 m across a table. Calculate the amount of work she does on the CD.

2. Tony pulls his wagon a distance of 15 m across the garden while applying a force of 160 N on the wagon’s handle. If the handle makes an angle of 400 with the horizontal, how much work did Tony do on the wagon?

3. What is the kinetic energy of a 1000 kg car traveling at 25 m/s?

4. A 65 kg diver is standing on a diving platform 10.0 m above the water. What is the gravitational potential energy of the diver with respect to the water’s surface?

Are your just typing random words out of your textbook?

What is the mathematical definition of work? i.e. write down an equation.

well if i knew the equations , i would be able to solve it.
i just know it has something to do with work-energy theorm
