Answer to Question #90334 in Mechanics | Relativity for Amarachi Michelle Ndu-Nwankwo

Question

Two seconds after you begin observing a swinging pendulum , the tip of the pendulum is at its rightmost position of 5m from center. Three seconds after that, it is at its leftmost position (5m from center) Determine an equation that models the horizontal position over time.

Answer 1

Simple Pendulum Equation

$$x(t)=A*sin(\omega*t+\phi)$$

where

$$A=5$$

$$\omega=2\pi/T=2\pi/5$$

$$\phi=0$$

so

$$x(t)=5*sin2\pi/5*t$$
