Question

a body of mass 6kg is moving along the smooth horizontall surface with a certain velocity.A force of 36 newton applied to this body opposite to its direction of its motion the force reduced the velocity of the body to half of the initial velocity when the body moves 9 meters. calculate how long does it take to occur also calculate the initial velocity​

Answer 1

Explanation:

m=6kg,

f=36N,

u=x

v=x/2

d=9m

a=x/2

f=ma

=)36=6 × x/2

=)x/2=6

=)x=12
