Determine the net force necessary to give an object with 3.6 kg an acceleration of 6.0 m/s^2.

We need 21.6 N to give acceleration of to an object of mass 3.6 kg

Explanation:

We have given mass m = 3.6 kg

Acceleration

We have to find the force required to give an acceleration of  

According to second law of motion we know that force = mass ×acceleration

So force required = 3.6×6 = 21.6 N

So we need 21.6 N to give acceleration of to an object of mass 3.6 kg
