Question

acts on a body of mass 5 kg and change its velocity from 8 metre per second from 12 metre per second in 4 second what is the magnitude of force​

Answer 1

$\large\fcolorbox{red}{cyan}{Force=5\:Newton}$

Explanation:

• Initial Velocity(u) = 8 m/s

• Final Velocity(v) = 12 m/s

• Time Taken(t) = 4 s

• Mass = 5 kg

• Accleration = ?

• Force = ?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First Lets Calculate The Accleration :-

$= > \bf \color {red}{accleration = \frac{v - u}{t} } \\ = > \frac{12 - 8}{4} \\ = > \frac{4}{4} \\ = > \boxed{1}$

Thus The Accleration is 1 m/s²

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now Lets Calculate The Force :-

=> Force = Mass x Accleration

=> 5 x 1

=> 5 N
