Question

what is a force acting on a body of mass 25 kg moving with a constant velocity of 10 M per second​

Answer 1

Answer:

force is zero

Explanation:

as the velocity is constant so acceleration is zero

so, f = ma

f = 25× 0

f= 0

Answer 2

The  force acting on a body of mass 25 kg moving with a constant velocity of 10 m per second​ will be 0 Newton.

Explanation:

Given:

A body of mass 25 kg moving with a constant velocity of 10 m per second​.

To Find:

The  force acting on a body of mass 25 kg moving with a constant velocity of 10 m per second​.

Solution:

We know, that acceleration is the rate of change of velocity.

That is,Acceleration, $a=\frac{dv}{dt}$

Now, if acceleration is 0, we have

$\frac{dv}{dt} =0$, which implies that v is constant.

Hence it is possible for a body to have zero acceleration and non zero velocity.

From Newton's second low

$F=m\times a$

a=0   and m=25kg.

$F= 25\times0$

   $= 0\ Newton.$

Thus,the  force acting on a body of mass 25 kg moving with a constant velocity of 10 m per second​ will be 0 Newton.
