Question

A body of mass 2kg is moving on a smooth floor in straight line with a uniform velocity of 10m/s.Resultant force acting on the body is(in N)_____.plz explain with equation

Answer 1

the velocity is constant so acceleration is 0..

now force =mass × acceleration

force =0

Answer 2

mass m = 2 kg

Since ,body is moving with a uniform velocity,i.e., there is no change in velocity throughout

Therefore, acceleration (rate of change of velocity ) a= ( v- u )/ t =>

0/t => 0 m/s^2.

Force F =m*a

=2 kg * 0m/s^2

=0 kg m/s^2 = 0 N.
