Question

A particle executing SHM has a time period of 2 seconds. If it starts from rest at a distance of 25 cm from the mean position, determine the maximum velocity and the
velocity when it has travelled 10 cm.​

Answer 1

Answer:

p(X)=p(-3)

therefore X=-3

x+3=0 ( you told me)

let put the Value of X=-3

X²+kx-2 = -3×-3+k×-3-2

9-3k-2

7-3k

-7=-3k

7=3k

k=7/3
