Question

11. A net force of 15N is exerted on an encyclopedia to cause it to accelerate at a rate of 5 m/s2.

Determine the mass of the encyclopedia.

Answer 1

3 kg

Step-by-step explanation:

We know that Fnet = ma. We are givel the net force and the acceleration, so we are able to rearrange for the mass.

m = Fnet / a = 15 / 5 = 3 kg
