Question

a bus of mass 500 kg starts from rest and rolls down the hill.if it travels a distance of 200m in 10s.calculate the acceleratin and force​

Answer 1

Answer:

Here

u=0m/s

s=200m

t=10s

so, v=?

Now

s=u+v/2*t

200m=o+v/2*10

v=40m/s

Again

a=v-u/t

=40/10

=4m/s^2

Hence

force=m*g

=500*9.8

=4900N
