The height (in feet) attained by a rocket t seconds into flight is giving by the function

h(t)= -1/3t^3 + 16t^2 + 33t + 10

When is the rocket rising?

When is the rocket decreasing?

when does it reach its maximum height above the ground?

what is the maximum height?

what is the velocity and when does maximum velocity occur?
