An object is accelerating at 175 m/s2. If the net force is tripled and the mass of the object is doubled, what is the new acceleration?
Please note that I can write this:
a1 = F1/M1, where a = 175 m/sec^2, F1 is the magnitude of the force which is acting on the particle, whose mass is M1.
Now I consider a force acting on the particle whose magnitude is F2= 3 F1, and the mass of that particle is M2 = 2 M1, so I can write, for the new acceleration a2:
a2 = F2/M2= (3 F1)/ (2* M1) = (3/2) * (F1/M1) = (3/2) * a1 = (3/2)* 175
soo a2 = (3/2) a1 = (3/2) *175 = 262.5 m/sec^2
