Question

A truck of mass 7000kg starts from rest and rolls down a hill with a constant acceleration. It
travels a distance of 400m in 20sec. Find the acceleration and force acting on it.

Answer 1

Answer:

Explanation:

m = 7000kg s = 400m t = 20 sec u = 0

v=? f=? a=?

v= s/t

v= 400/20

v= 20m/s

a = v-u/t

a = 20-0/20

a=1

force=m*a

force= 7000*1

force = 7000N

mark me as brainliest
