In summary, the conversation is about a person who needs help with their assignment which is due on April 7th. They have completed most of the questions but still have four left. The remaining questions involve calculating work, kinetic energy, gravitational potential energy, and the mathematical definition of work. The person is also seeking clarification on the concept of work, energy, and power. They have been provided with a resource to refer to and are apologizing for their initial tone.

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.
