A force gives a 2.0 kg mass an acceleration of 5.0 on a level surface What is the force applied to the mass?

The force applied to the mass can be calculated using Newton's second law: force = mass x acceleration. Plugging in the values, we get force = 2.0 kg x 5.0 m/s^2 = 10 N. So, the force applied to the mass is 10 Newtons.
