Question

A block with mass m = 7.4 kg is attached to two springs with spring constants kleft = 31 N/m and kright = 53 N/m. The block is pulled a distance x = 0.27 m to the left of its equilibrium position and released from rest.

7)

Where is the block located, relative to equilibrium, at a time 1.06 s after it is released? (if the block is left of equilibrium give the answer as a negative value; if the block is right of equilibrium give the answer as a positive value)

8)

What is the net force on the block at this time 1.06 s? (a negative force is to the left; a positive force is to the right)

9)

What is the total energy stored in the system?
