Question

A force of 20 N acts upon a body whose weight is 9.8 N. What is the mass of the body and how much is its acceleration ? (g = 9.8 m/ s^2).​

Answer 1

Solution :-

Weight ( W ) = 9.8 N

g = 9.8 m s-²

Weight (W) = Mass × Acceleration Due To Gravity

W = MG

Mass of the body ( m ) = W / g

= 9.8 / 9.8

= 1 kg

Force = Mass × Acceleration

So,

Acceleration = Force / Mass

= 20 / 1

= 20 m/s²
