5-5.

Use the equation, h(t), that you found in problem 5-1 to find the height of the spitwad after 2 seconds.

'How fast' could refer to velocity or speed. Be sure that you are clear in your answer.

x(t) = 10

v(t) = −10

$(\text{show steps})=\frac{37}{16}\text{ seconds}$

The spitwad will be at its highest point at the moment when its velocity changes from positive to negative.
