Question

Antonio (883 N) does a push-up lifting his body a total of 0.6 meters (down and back up). If this process generated 375 Watts of power, how long did it take her to complete the push-up?

Answer 1

Time = 1.413 seconds.

Step-by-step explanation:

Given the following data;

Force = 883N

Distance = 0.6m

Power = 375 Watts

To find the time;

First of all, we would find the work done by Antonio.

Workdone = force * distance

Workdone = 883 * 0.6

Workdone = 529.8 Joules.

Now, to find the time;

Time = workdone/power

Substituting into the equation, we have

Time = 529.8/375

Time = 1.413 seconds.

Therefore, it took her 1.413 seconds to complete the push-up.
