Question

A 185-g object is attached to a spring that has a force constant of 75.5 N/m. The object is pulled 8.75 cm to the right of equilibrium and released from rest to slide on a horizontal, frictionless table. Calculate the maximum speed of the object. Number m/s Find the locations of the object when its velocity is one-third of the maximum speed. Treat the equilibrium position as zero, positions to the right as positive, and positions to the left as negative Number Number cm cm

Answer 1

When the spring is stretched it starts oscillating between maximum elongation to neutral position and then to maximum compression from right to left.

It's maximum velocity will be at natural position of spring at x=0.

Calculation is as shown below.
