Question

a force of 20 Newton act upon a body weight is 9.8 Newton what is the mass of the body and how much is its acceleration

Answer 1

Given :
Force = 20 N
Weight = 9.8 N
To Find :
Mass of the body
Acceleration of the body

Solution :

As we know ,
Weight = Mass × Gravity
9.8 = Mass × 9.8
9.8/9.8= Mass
Mass = 1

And ,

Force = Mass × Acceleration
20 = 1×Acceleration

Acceleration = 20 m/s² .

Thanks !!
