Question

When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object with mass 4 kg, the acceleration of the object is 13 m/s^2. When the same force acts upon another object, its acceleration is 2 m/s^2. What is the mass of this object?

Answer 1

26 kg

Explanation:

varies inversely :

y = k/x

acceleration = k/mass

13 = k/4

k= 52

---------------------

2 = k/mass

2 = 52/mass

mass = 26 kg
