Question

The ratio of maximum velocity to the velocity of a
particle performing S.H.M. at a point where
potential energy is 75% of total energy is
(1)2:√3
(2).2:1
(3) 1:2
(4) 1:√3​

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.
