Question

a man pushes a box mass of 50 kg with a force of 18 N. What will be the acceleration of the box due to this force. What would be the acceleration if the mass were doubled

Answer 1

Since,
F=ma
Therefore,
50 * a = 18
a = 18/50 = 9/25
a = 0.36 ms¯²

Now, mass = 100
Therefore
a = 18/100
a = 0.18 ms¯²

Answer 2

Accelaration when 18N of force is applied in 50 kg mass of box
Force = Mass × Accelaration
18 = 50 × Accelaration
Accelaration = 18 / 50 = 0.35 m/s^2

Accelaration when mass is doubled,
Force = Mass × Accelaration
18 = 100 × Accelaration
Accelaration = 18 / 100 = 0.18 m/s^2
