Question

a body of mass 2 kg has velocity 9m/s. what force is needed to bring it to hat 9 m​

Answer 1

HEYA......✌✌✌✌✌

HERE IS YOUR ANSWER...........

Given:

m = 2 kg

v = 9 m/s

d = 9 m

we know that,

velocity = displacement / time

so,

Time = displacement / velocity

Time = 9 / 9

Time = 1sec

so,

acceleration = velocity / time

acceleration = 9 /1

acceleration = 9m/s^2

ACCORDING TO NEWTON'S SECOND LAW OF MOTION,

Force = mass × acceleration

Force = 2 × 9

Force = 18 N
