Suppose that a constant force is applied to an object with a mass of 12kg, it’s creates an acceleration of 5m/s^2. the acceleration of another object produced by the same force is 4m/s^2, what is the mass of this object?

Mass of second object will be 15 kg

Explanation:

We have given mass of first object = 12 kg

Acceleration

According to second law of motion we know that force F = MA

So force

As the same force is applied to the second object of acceleration

So force = ma

m = 15 kg

So mass of second object will be 15 kg
