it is actually given to us like this in our formula sheet . (am talking about the on i used, not the one the book ) thanks xiaoB, but i was talking about the velocity equation that the book used

but where did he get that formula from ?

Homework Statement x = 0.20m*sin(0.44 rad/s * t) Write the equation for the velocity of this object. Find the velocity at t = 4:0 s. Homework Equations The Attempt at a Solution well, i know that v(t)= - wAsin(wt +\phi) and we know the w = 0.44 rad/s A = 0.20 s t=4...
