The amplitude of small oscilliations for the bob is x_{0}, and the amplitude of small oscilliations for the cart is y_{0}. The length of the pivot is l . What is the maximum velocity of the bob relative to the Earth ?

2. Relevant equations

x=x_{0}sin(wt)

y=y_{0}sin(wt)

3. The attempt at a solution

I tried taking derrivatives of the functions stated above, thus finding velocity as a function of time, and then adding those two velocity vectors using the law of cosines. (The length of the pivot is needed for finding the angle between the vectors)
