The displacement - time graph of a particle executing SHM is shown in figure. Which of the following statements is//are true ?

A

(a)The velocity is maximum at `t = T//2`

B

(b)The acceleration is maximum at `t = T`

C

(c)The force is zero at `t = 3T//4`

D

(d)The kinetic energy equals the total oscillation energy at `t = T//2`

Text Solution

Verified by Experts

The correct Answer is:
B, C
`v or KE = 0` at `y = +- A`
`v` or `KE =` maximum at `y = +- 0`
`F` or a is maximum at `y = +- A`
`F` or a is zero at `y = 0`
