Homework Statement
Okay.. so I have tried to do this one but no luck.
Homework Equations
w= 2 * pi* v
1/2 kA^2= 1/2mv^2 + mgh
Alright so the question:
The motion of a particle is given by x(t)= 25cm* cos 10t
What time is the kinetic energy twice the potential energy?
Not sure how to use a x(t) equation to incorporate mgh which deals motion in the y direction.
Any guide would be appreciated.. Thanks!
