Hello!

An athlete has a mass of 45 kg, moving at the rate of 10 m/s towards the finish line. what is the momentum ?

We have the following data:

p (momentum) = ? (in kg.m/s)

m (mass) = 45 kg

v (velocity) = 10 m/s

We apply the data to the momentum formula, see:

_______________________

Let speed is equal to the distance over time.

r =

where:

r is the average speed

d is the distance travelled

time is the total time interval

Solution:

d = 820 km

t = 27 hrs
