Question

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?

Answer 1

Mass of second object will be 15 kg

Step-by-step explanation:

We have given mass of first object = 12 kg

Acceleration
`a=5m/sec^2`

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

So force
`F=12* 5=60N`

As the same force is applied to the second object of acceleration
`a=4m/Sec^2`

So force = ma

`60=m* 4`

m = 15 kg

So mass of second object will be 15 kg
