Question

A body of mass 1kg is moving along a straight line with a velocity of 1 ms . The external force acting on the body is ?

Answer 1

the body experiences an external force of 0 N as the acceleration of the body is 0 m/s2
f = ma

please select it as the brainliest answer

Answer 2

Answer: 0 Newton

Given velocity = 1m/s  

Mass of the body = 1 Kg  

According to Newton's law,

                  $Force\quad =\quad Mass\quad \times \quad Acceleration\quad =\quad m\quad \times \quad a\quad \longrightarrow (1)$

We know that, acceleration = rate of change of velocity.  

But here it is given that the velocity is 1 m/s and therefore there is no change in velocity which means acceleration is 0.

Hence (1) becomes,

                  $F\quad =\quad \left( 1 \right) \quad \times \quad 0\quad =\quad 0\quad Newton$
