Question

A force of 20 N moves a body with an acceleration of 2 ms What is its mass?​

Answer 1

Explanation:

Weight = 9.8 N

W=m×g

9.8=m×9.8

m = 1 kg

Force, F=mass×acceleration

=20N=1Kg×a

Acceleration,a=20m/s 2

Answer 2

Answer:

10 kg

Explanation:

given, F = 20 N

acceleration,a = 2 m/s

we know F = ma

or, m= F/a = 20/2 = 10 kg
