## Homework Statement

A small cart of mass .8 kg is attached to one end of a horizontal spring as shown in the figure. The spring constant is 600 N/m. When the spring is stretched by .05 m and the car is released from rest, the car oscillates back and forth. The friction is negligible. Ignore the mass of the spring.

A) Find the angular frequency of oscillations in HZ.

B) Find the maximum velocity of the block.

C) Find the total energy of the system at the point where acceleration is zero.

## Homework Equations

Angular frequency = 2(3.14)F

## The Attempt at a Solution

Pretty lost, if anyone could guide me to what formulas to use or what way to attack this problem I would be very grateful. Thanks
