1. The power in delivering the load is 13,230 Watts.

2. The power developed from a jumbo jet is 25 Mega Watts or Watts.

Explanation:

Power is the time rate at which work is done.

Useful Conversions:

1 horsepower (hp) = 550 ft.lb/s

1 hp =746 Watts

Formula for Power is: equation 1 equation 2

where is power, unit is in Watts (metric) or horsepower, hp (British system) is work, unit is in Newton-meter (N.m) or Joules (J) is velocity, unit is in m/s is time, unit is in seconds

Formula for Work is: where is work done on a body, unit is in N.m or Joules is force, unit is in Newtons (N) is the distance, unit is in meters (m)

Formula for Force is: where is the force, unit is in Newtons (N) is the mass, unit is in kg is the acceleration due to gravity equal to 9.8 1. Solving for the power for problem #1 with the following given: , , , a. Solve first for the force, we get:   b. Then, substitute the force to solve for work, we get:   c. Now, substitute the answer of work to the formula for power, we get:   2. Solving for power in problem #2 with the following given: , , a. Solving the power using equation 2, we get:    or or mega Watts
