When a constant force acts upon an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 7 kg, the acceleration of the object is 8 m/s^2. If the same force acts upon another object whose mass is 4 kg, what is this object's acceleration?

Answer :

F = m.a

F = 7.8 = 56 N

56 = 4.a

a = 14 m/s²
