Answer:
Gymnasts always perform on padded mats because
- The padded floor increase the time. The time changes because the padded floor extends the time of the collision. The force is reduced by this time change.
Step-by-step explanation:
- The Impulse Momentum Theorem states that the change in momentum of an object is equal to the impulse applied on it.
J = Δ P ---- (1)
Where J is impulse and Δ P is change in momentum
We also know that impulse is the net force applied on a object which is represented by the following equation:
J = F ΔT
Putting this equation in equation (1), we get:
F ΔT = Δ P
So, this shows when the time is increases then the impulse decreases due to which the gymnasts always perform on padded mats.

50 calories are consumed per milefor 15 miles per hour, calories consumed
= 50*15
=750 calories per hour,
this is equal to 750/3600
= 0.2083 calories/second, given that,
1 calorie per sec
= 4.19 watt, the average power output
= 0.2083*4.19
= 0.873 Watts
