Climbing with Hank

You and a friend are hiking in the mountains. You want to climb to a ledge that is 20 ft above you. The height of the grappling hook ca be thrown is given by the function h = -16t^2 - 32t + 5. What is the maximum height the grappling hook can reach? Can you throw it high enough to reach the ledge?

Shouldn't it tell you how long it is on the packaging?

It's not funny anymore, Hank.
