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?

Respuesta :

Answer:

Mass of second object will be 15 kg

Explanation:

We have given mass of first object = 12 kg

Acceleration [tex]a=5m/sec^2[/tex]

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

So force [tex]F=12\times 5=60N[/tex]

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

So force = ma

[tex]60=m\times 4[/tex]

m = 15 kg

So mass of second object will be 15 kg
