Question

A block on a horizontal spring is released from rest after being displaced to the left at $t = 0$ . Using $x = A sin (ω t + ϕ)$ with $x$ positive to the right, find the phase angle when it first passes through the equilibrium position.

Options:

Answer:

D

Solution:

At $t = 0$ , $x = - A$ , so $ϕ = 3 π /2$ . It first reaches $x = 0$ when the phase is $2 π$ .
