Answer
given,
height of Alpe d'Huez = 1100-m
time = 37.5 min
mass of the rider and his bike = 65 Kg
the metabolic power to ride = 700 W
U = m g y
U = 65 x 9.8 x 1100
U = 700700 J
since efficiency is 25%
b)
P = 1245.68 W
Answer:
Yes
Explanation:
The displacement covered by a body in unit time is called velocity.
