Question

A block performs SHM and its equation is given as

x = 4 + 5 s i n π t

. Which of these would be its correct representation?

Options:

Answer: Option A
:
B
Equation

x = 4 + 5 s i n π t

Since the phase doesn't' have any phase constant φ so at t = 0 particle was at its mean position.

X = 4 + 5 s i n π 0 = 4

So x = 4 is particle's mean

x = A s i n ω t

Coefficient of x is A which is Amplitude Which here is 5 so option (b)
