Your town is thinking about building a nuclear power plant. you will be asked to vote on it. which source would provide the most reliable information about the safety of nuclear power plants? select one: a. the nuclear regulatory commission b. your local newspaper c. the company that is going to build the plant d. the mayor of another town that already has a nuclear plant

a) 75000Joules

b) 0Joules

Explanation:

Workdone = Force * Distance

Given

distance= 750m

Force = 300N

a) If the frictional force = 200N

The Total force = 300N - 200N = 100N

Work done = 100 * 750

Workdone = 75,000Joules

Hence the workdone if the force of friction is 200N is 75,000Joules

b) If the frictional force = 300N

The Total force = 300N - 300N = 0N

Work done = 0* 750

Workdone = 0Joules

Hence the workdone if the force of friction is 300N is 0Joules i.e no work will be done on the sled
