A particle vibrates in simple harmonic motion along a vertical line between y1 a

Question

A particle vibrates in simple harmonic motion along a vertical line between y1 and y2 as shown in the figure below. y = 0 is the equilibrium position. (Hint: Consider the relationship between acceleration and displacement for a particle in simple harmonic motion. Assume up along the screen is the positive direction.) Which of the following is true when the particle is at the highest point in its oscillation (y1)? (Select all that apply.) zero velocity maximum negative velocity maximum negative acceleration maximum positive velocity zero acceleration maximum positive acceleration Which of the following is true when the particle is at the equilibrium position (y = 0) and is on its downward journey? (Select all that apply.) zero velocity maximum negative velocity maximum negative acceleration maximum positive velocity zero acceleration maximum positive acceleration (c) Which of the following is true when the particle is at the lowest point in its oscillation (y2)? (Select all that apply.) zero velocity maximum negative velocity maximum negative acceleration maximum positive velocity zero acceleration maximum positive acceleration

Explanation / Answer

a) zero velocity,maximum negative acceleration b) maximum negative velocity ,zero acceleration c) maximum positive acceleration, velocity zero
