A 3.2 kg block is hanging stationary from the end of a vertical spring that is attached to the ceiling. The elastic potential energy of this spring/mass sytem is 1.5 J. What is the elastic potential energy of the system when the 3.2 kg block is replaced by a 5.7 kg block?

Step 1

The mass of the first block =m_{1}=3.2kg.

The elastic potential energy corresponding to block with mass m_{1}=U_{1}=1.5J.

Let m_{2 }be the second mass, and corresponding potential energy be U_{2}.

Write the expression for the potential energy of the spring

Step 2

Write the expression for the force acting on spring.

Step 3

Substitute equation (II) in (I) and write the expression for th...
