Velocity and height at each time interval

  • #1

Homework Statement



I want to calculate velocity and height at each time interval
Time intervals: 1,2,3 (seconds)

equilibrium height = 3 meters
amplitude = 0.2
angular frequency = 48 rad/s
phase shift = 60


Homework Equations



y(t) = equiheight + Amplitude*sin(angfre*t + phaseshift)

The Attempt at a Solution



I have no idea about where to start. Please help.

Hello MM, and welcome to PF.
You could start with the height, for which you have presented a relevant equation. Nothing stops you from filling in equiheight, Amplitude, angfre, t and phaseshift, right ?
Then, for v you will need another equiation. No idea whatsoever ?

Exactly. I know what you are saying about plugging everything in. What if we use Euler's algorithm to find the answer ? Any ideas about that ?

No can do: In the first place it isn't mentioned under 2. Homework Equations . :smile:
And if it were, why on earth would it belong there ?

Do you know what to do to determine the velocity when an expression for the position is given ?
(Hint: consider the definition of velocity)

Euler's algorithm is for numerical integration.

[edit] And: if you "know what you are saying about plugging everything in", please show it, just to be sure things go alright...
