#### 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}).

#### Solution

W (weight of the body) = 9.8N

m (mass of the body) = ?

g (acceleration due to gravity) = 9.8 m/s^{2}**W= mg**

9.8 = m × 9.8

9.8 /9.8 = m

1 = m

Answer: Mass = 1kg

F (force) = 20N

M (mass of body) = 1kg

F = m × a

20 = 1 × a

20/1 = a

a = 20m/s^{2}

Answer: Acceleration = 20m/s^{2}
