There are a couple of ways to do that but it depends on the context. If you have...

> a Position-Time graph, the steepest slope of the graph is the maximum velocity> a Velocity-Time graph, it's just the point farthest away from the x-axis> an Acceleration-Time graph, I find it easiest to sketch out a velocity-time graph on top by calculating the area between the acceleration line and the x-axis

 

If you're looking at a word problem, here are some of the equations that might help you find the peak velocity:

d = (v_f*t - 0.5at²)d = 0.5*(v_f+v_i)*tv_f² = v_i² + 2adE_k = 0.5*m*v²
