Question

For a body starting from rest, what will be the displacement in 10 seconds when the final velocity is 4m in 2 seconds?

Answer 1

Explanation:

initial velocity(u)=0m/s as the body starts from the rest

final velocity(v)

=4/2 m/s

=2m/s

time =10s

acceleration= v-u /t

=2-0/10

=2/10

=1/5m/s²

distance (s)

s= ut + 1/2at

=0*10 + 1/2*1/5*10

=0 + 1/2*2

=0 + 1

=1m(ans)
