how long does it take to reach it's maximum height?

what is the initial velocity , final velocity off the ball

initial height= 2.7m

max height=4.5m

I would do this with energy. You know the initial potential energy.... mghi, and the final potential energy mg*hmax. The difference represents the kinetic energy of the ball initally 1/2 m v^2

The final kinetic energy is equal to mg*hmax
