Question

A body vibrate in simple harmonic motion with a frequency of 50 Hz and an amplitude of 4cm .find a)the period b)the acceleration at the middle and at the edge of the path of oscillation c)the veloci

Answer 1

period = 1/f
y = 4sin(2πf x)
v = dy/dx
find a = dv/dx at x=0 and x=pi/2
note that a(x) = -y(x)
