Question

2. A particle is subjected to two simple harmonic motions.
X1 =4.0 sin (100nt)
and
X2 =3.0 sin 100nt +
TU
3
Find
(a) the displacement att =0
(b) the maximum speed of the particle and
(c) the maximum acceleration of the particle.​

Answer 1

Answer:

An acceleration can cause speed to increase, decrease, and even stay the same! Acceleration tells you the rate at which the velocity is changing. ... The acceleration can change the magnitude and/or the direction of the velocity. Speed is only the magnitude of the velocity.
