Question

What is the mass of a cannonball if a force of 2,500 N gives the cannonball an acceleration of 200m/s2?

Answer 1

Newton's 2nd law of motion:

                         Force = (mass) x (acceleration)

Divide each side
by 'acceleration':      Mass  =  (force) / (acceleration)

                                       =  (2,500 N)  /  (200 m/s²)

                                       =    12.5 kg

Answer 2

Well if you are looking for mass that'll be M=f/a which means mass equals force divided by acceleration so you divide force by acceleration 2500N/200m/s2 equals 12.5 kg
