Given:

A body of mass 1 kg moving on a smooth horizontal surface with velocity 5 metre per second is to be brought to rest in 5 seconds.

To find:

Magnitude of force ?

Calculation:

  • First , let's find out the acceleration of the object.

a =  \dfrac{v - u}{t}

 \implies \: a =  \dfrac{0 - 5}{5}

 \implies \: a =  \dfrac{- 5}{5}

 \implies \: a =  - 1 \: m {s}^{ - 2}

Now, force will be :

F = m \times a

 \implies \: F = 1 \times ( - 1)

 \implies \: F =  - 1  \: N

So, magnitude of force needed is 1 N.
