A 5 N ball is connected to two identical springs with spring constants k = 1.0 × 10^1 N/cm that push/pull in opposite directions and slides on a friction less surface. The ball is initially stationary and is then moved a distance x= 7 cm to the right and released from rest.

A) Find the magnitude and direction ( or -) of the net force on the ball just as it is released.

B) What is the potential energy of the system as it is released?

C) Find the maximum speed of the ball.
