Answer:
1
Step-by-step explanation:
Method 1: Graph, then look at positive zero because time cannot be negative.
Method 2: You just want to find time when the height is zero, so if you set h at zero, you find it is a quadratic; from there you can factor, graph, or use the quadratic formula to solve.
