Question

How much force is needed to produce an acceleration of 20ms^2 in a body of mass 500gm

Answer 1

Explanation:

a=20m/s^2

mass=500gm=500/1000kg=0.5kg

now,

f=m×a

=0.5=×20

=10N

or 10kgm/s^2

Answer 2

Answer:

10N

Explanation:

a=20$m/s^{2}$

m=500g=$\frac{500}{1000}$=0.5kg

force=mass×acceleration

f=0.5×20

f=10N

The force is 10N or 10kg$m/s^{2}$
