Oscillations
The displacement of an object attached to a spring and executing simple harmonic motion is given by x = 2 × 10-2 cos πt metres. The time at which the maximum speed first occurs
-
0.5 s
-
0.75 s
-
0.125 s
-
0.325 s
A.
0.5 s
x = 2 x 10-2 cos πt
v = 0.02 π sinπt
v is maximum at t = 1/2 = 0.5 sec

A coin is placed on a horizontal platform which undergoes vertical simple harmonic motion of angular frequency ω. The amplitude of oscillation is gradually increased. The coin will leave contact with the platform for the first time
The function sin2(ωt) represents
The bob of a simple pendulum is a spherical hollow ball filled with water. A plugged hole near the bottom of the oscillation bob gets suddenly unplugged. During observation, till water is coming out, the time period of oscillation would
