Homework Statement
Object A and B are placed on a spring. Object A has twice as much mass as object B. If the spring is depressed and released, propelling the objects into air, object A will:
answer: rise to the same height as object B
Homework Equations
The Attempt at a Solution
Based on my reasoning and math, I am confused why both objects would rise to the same height:
The force on both objects is the same, F. And 2*mass of B = mass of A
F = (mass of A)*(accl. A) = (mass of B)*(accl. B)
F = 2*(mass of B)*(accl. A) = (mass of B)*(accl. B)
cancel out (mass of B):
F = 2*(accl. A) = (accl. B)
Since the upward acceleration of B is twice the that of A, why would the height be the same?
