Question

The position of a SHO as a function of time is given by x=3.5cos(5πt/4+π/6) where t is in seconds and x in meters. Find the position at t=0. Find the velocity at t=0. Find the velocity at t = 2.2 s

Find the acceleration at t = 2.2 s

  • To find position just plug in t=0 in the given equation. To find velocity first find the derivative of position function and after that plug in t=2.2 in the new equation. To find the acceleration find the second derivative of position function (or first derivative of velocity function) and plug in t =2.2 s in the new equation. Nika commented over 3 years ago
