Simple harmonic motion

Question

A body is executing simple harmonic motion with an angular frequency $2 rad / s$ . The velocity of the body at 20 mm displacement, when the amplitude of motion is 60 mm, is

Easy

A

$40 mm / s$
B

$60 mm / s$
C

$113 mm / s$
D

$120 mm / s$

Solution

$v = ω \sqrt{(a^{2} - y^{2})} = 2 \sqrt{60^{2} - 20^{2}}$ $= 113 mm / s$
