The displacement of a particle executing SHM is given by y = 0.25 (sin 200t) cm. The maximum speed of the particles is:
1. 200 cm/sec
2. 100 cm/sec
3. 50 cm/sec
4. 0.25 cm/sec
A particle undergoes SHM with a time period of 2 seconds. In how much time will it travel from its mean position to a displacement equal to half of its amplitude?

A second's pendulum is mounted in a rocket. Its period of oscillation decreases when the rocket:
(1) Comes down with uniform acceleration
(2) Moves around the earth in a geostationary orbit
(3) Moves up with a uniform velocity
(4) Moves up with the uniform acceleration
