Question

Question Name Vertical Oscillator 2 A metal ball of mass m is hanging from a vertical spring with elastic constant k = 20 N/m near the surface of the earth. In equilibrium, the spring is stretched by 10 cm relative to the relaxed length of the spring. The spring is then compressed by 1 cm relative to the equilibrium position and is released into oscillation at time t =0. The height of the object relative to the equilibrium height oscillates as shown below as a function of time. Determine at which point in time the acceleration is maximal.

Explanation / Answer

at B and C , the ball is at maximum displacement or at its extreme position. hence acceleration is maximum there .
