Formula for power -
Power = $\frac{Work}{Time}$

Power Calculator calculates the value of known parameters in the power formula and calculates the unknown parameters.

## Step by Step Calculation

Step 1 :

The quantity of work to do with a force which cause a displacement.

Power :

P = W / T .

Work :

W = P * T .

Time :

T = W / P .

Step 2 :

State the equation you plan to use and plug in the values.

## Example Problems

1. ### The tired monkey (mass of approximately 1kg) it push-ups by applying a force to elevates center of the mass by 5 cm in order to do a 0.50 joule of work.If the tired monkey do all this work in 2 seconds.then determine the power.

Step 1 :

The given:

Work (W) = 0.50 .

Time (s) = 2.0

Power (P) = ?

Step 2 :

Substitute the given values in the formula.

Power :

P = W / T .

P = 0.50 / 2.0

Power = 0.25 watts.

2. ### When doing push-up, a man lifts his 42.0 Kg body and a distance of 0.25 meters in a 2 seconds.What is the power delivered by a man's chest.?

Step 1 :

Here first we need to find 'Work'.

The given:

Time (s) = 2.0 s

Work (W) = ?

Power (P) = ?

mass (m)= 42.0 kg convert in to Force (F) = 411.6 N

displacement (d) = 0.25 meters

Step 2 :

W = F * d.

W = 411.6 * 0.250 ,

W = 102.9 J

Power :

P = W / T .

P = 102.0 / 2.0
