An object on a vertical spring oscillates up and down in simple harmonic motion with an angular frequency of 14.2 rad/s. calculate the distance d by which the spring stretches from its unstrained length when the object is allowed to hang stationary from it.

When an object moves in uniform circular motion, the direction of its acceleration is a) in the same direction as its velocity vector. b) in the opposite direction of its velocity vector c) is directed toward the center of its circular path. d) is directed away from the center of its circular path. e) depends on the speed of the object.
