Question

expression for velocity of rolling body moving down the inclined plane​

Answer 1

Explanation:

the force required to move the body up an inclined plane can be calculated as

Fp = W h / l

= W sin α

= m ag sin α (1)

where

Fp = pulling force (N, lbf)

W = m ag

= gravity force - or weight of body (N, lbf)

h = elevation (m, ft)

l = length (m, ft)

α = elevation angle (degrees)

m = mass of body (kg, slugs)

ag = acceleration of gravity (9.81 m/s2, 32.174 ft/s2)

By adding friction - (1) can be modified to

Fp = W (sin α + μ cos α)

= m ag (sin α + μ cos α) (2)

where

μ = friction coefficient
