Question

A force of 20 Newton acts upon a body whose weight is 9.8 N. What is the mass of the body and how much is the acceleration.

Answer 1

Hi !

Force = F = 20 N

Weight = mg = 9.8 N

Mass = m

9.8 = mg
9.8 = 9.8m , m = 1

mass = m = 1 kg

-----------------------------------------------------
acceleration = a

we know that ,
F = ma
20 = 1a
a = 20 m/s²
