Subject: Acceleration of More Massive Object

A 10-kg object accelerates at 60 meters per second squared. 
What would be the acceleration of a 30-kg object?

In order to calculate the acceleration of a body you have to know two 
things: the net force acting on the body and the mass of the body.  
The acceleration is then calculated using the formula a=F/m  So, if 
your 10 kg object accelerates at 60 m/sec^2, the force must be 600 
newtons. Your question cannot be answered unless I know the force 
acting on the 30-kg body. If you assume that the same force acts on 
both bodies, then the acceleration is 20 m/sec^2.
