Q2. What do you know about runner power & explain impulse momentum principle
Ans. 
Runner power is the amount of work done by a runner in a given time. Impulse momentum principle states that the change in momentum of an object is equal to the impulse applied to it.
• Runner power is a measure of how much work a runner can do in a specific time period.

• It is calculated by dividing the work done by the time taken.

• For example, if a runner completes a 10 km race in 1 hour, their power can be calculated by di...read more
