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

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