Power And Force
A cyclist maintains constant power P while climbing of slope at constant speed v. Component of force along motion is:
Select the correct option:
Solution
P/v
From the instantaneous power formula P=F⋅v, if the force and velocity are in the same direction: P=F⋅v Since both P and v are constant, the force applied along the direction of motion must be: F=vP. This force must overcome the components of gravity and friction.

Solution
Correct Answer:
P/v
From the instantaneous power formula P=F⋅v, if the force and velocity are in the same direction: P=F⋅v Since both P and v are constant, the force applied along the direction of motion must be: F=vP. This force must overcome the components of gravity and friction.
