Homework 1/19 with solution

The altitude (in feet) obtained by a model rocket t seconds into flight is given by the function:

h(t) = -(1/3)t^3 + 4t^2 + (20)t +2

Find the maximum altitude attained by the model rocket, and the time it reaches that height.

The max. height is reached when the first derivative of the given function = 0.

(I am sure you know that t-cubed is written as t^3 sometimes.)

Solution:  model rocket
