You attach a 150 g mass on a spring hung vertically. a. If the spring initially stretches 16 cm when you hang the mass on it, what is the spring constant? b. How long will one oscillation take? The spring is now oriented horizontally and attached to a glider on a frictionless airtrack. The glider also has mass of 150 g. You want to observe the oscillations of this horizontal springmass system in the lab with a motion detector. You...

A block of mass m = 6.04 kg is attached to a spring with spring constant k = 1572 N/m and rests on a frictionless surface. The block is pulled, stretching the spring a distance of 0.170 m, and is held still. The block is then released and moves in simple harmonic motion about the equilibrium position. (Assume that the block is stretched in the positive direction.) (a) What is the frequency of this oscillation? 2.57 Hz (b) Where is...
