Question

a person completed their sprint, and their time at 60m was 8.55 seconds. if this person weighs 99 kg, find their horizontal power (w)

Answer 1

Step-by-step explanation:

P =F x d / t

P = (mg) x d / t
p= ( 99 x 9.81 ) x 60 / 8.55
p= 6815.4 W

Check:
P= FV
F= mg
P = ( 99 x 9.81 ) x (60 /8.55)
p= 6815.4 W
