Question

A 2.00-kg object is free to slide on a horizontal surface. The object is attached to a spring of spring constant 300N/m , and the other end of the spring is attached to a wall. The object is pulled in the direction away from the wall until the spring is stretched 50.0mm from its relaxed position. The object is not released from rest, but is instead given an initial velocity of 2.50m/s away from the wall. Ignore friction.

Given:

Energy of oscillating system = 6.63J

A = 210mm

The object is pulled in the direction away from the wall until the spring is stretched 50.0mm from its relaxed position. The object is not released from rest, but is instead given an initial velocity of 2.50m/s away from the wall. Ignore friction. Given: Energy of oscillating system = 6.63J Object's position x as a function of time = Phii = ? -pi

Explanation / Answer

The stored elastic potential energy in the spring when it is compressed 0.05 m is:
Ep = k ? x
