Question

A body of mass 10kg starts from rest and rolls down an inclined plane it rolls down 10m in 2sec calculate what is the acceleration attained by the body, what is the force acting on the body and what is the velocity of the body

Answer 1

velocity is 5m/s and force20N

Answer 2

Answer:

Given ,

m =10kg

initially velocity (u) = 0m/s

distance (s) = 10 m

time( t) = 2sec

Explanation:

To find,

acceleration attend by the body

force acting on the body

velocity of body

applying position time equation

s = ut + 1/2 at²

10 = 1/2 *a*2²

= 1/2 *4*a

10 = 2a

a = 5m/s²

now

force = mass * acceleration

f = (10*5) N

f = 50 N

now applying velocity time equation

v = u+ at

v = 0 + 5*2

v = 10 m/s
