Question

A force of 20N acts upon a body whose weight is 9.8N. What is the mass of the body and how much is its acceleration?(g=9.8m/s2)

Answer 1

given f=20,w=mg,g=9.8,so mass=1kg.f=ma,20=1×a,a=20m/s²

Answer 2

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
