Question

a body of mass 5 kg is moving with an acceleration of 2 metre per second square calculate the force required to stop the body​

Answer 1

the force required will be frictional force or negative...

f=m ×a

f= -(5 × 2)

f= -10N

Answer 2

__________________________

F=5 x 2

$\implies$F=10Newton

•But to Stop the Body The Force Will be Negative.

Therefore

$\implies$ Force =-10 N
