Answer 2

Given,

Riya can do 100 push-ups in 2 minute.

To find,

Number of push-ups and amount of work, done by her in 5 minutes.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Riya can do in,

2 minutes = 100 push-ups

1 minute = 50 push-ups

5 minutes = 50×5 = 250 push-ups

Now, if we consider the definition of work done according to the Physics, we have to calculate the displacement and multiply the value of displacement with the value of applied force.

Here, the displacement of Riya is more or less zero, because she's doing push-ups in a stationary position.

That's why work done will be

Work done = F × S = F × 0 = 0 joules

Hence, she can do 250 push-ups in 5 minutes but the work done will be 0 Joules.
