Question

composition of two simple harmonic motion in the same straight line

Answer 1

spring exhibits a simple harmonic motion
x = A×sin(wt)
where w = 2.pi/T
where T = 2.pi.sqrt(m/k)
m is mass k is spring const

A pendulum with small oscillations exhibit straight line SHM
x=Asin(wt)
w=2pi/T
T=2.pi.sqrt(L/g)
L is length g is acceleration due to gravity
