According to Newton's Second Law of Motion, the acceleration 'A' produced by a constant force varies inversely with the mass 'M' of the object to which the force is applied. A constant force acting upon an object with mass 2 kg produces an acceleration of 16 m/s2. The acceleration of another object produced by the same force is 8 m/s2. What is the mass of this object?

F=ma this is it
Find first F=m1a1
Then m2=F/a2=m1 (a1/a2) = 4kg

F = m1 x a1 = 2 x 16 = 32 N
F = m2 x a2
m2 = F / a2 = 32 / 8 = 4 kg

F = ma
for obj. one...
F = 2 kg * 16 m/sec^2
F = 32 kg-m/sec^2
for obj. two
32 kg-m/sec^2 = m * 8 m/sec^2
m = 32 kg-m/sec^2 / 8 m/sec^2 = 4 kg
