Question

1. The displacement in a simple harmonic motion is given by
y = 2 cos(50nt + T'/4) m find
a) The amplitude of SHM
b) The phase constant
c) Angular frequency
on for the following quantities and eyr​

Answer 1

Explanation:

compare with genral equation

y = acos (Wt + phi)

amplitude a= 2

phase constant phi = T'/4

angular velocity

W = 50n
