Question

An object is thrown upward and has a height, h, in feet, t seconds after it is thrown, represented by h = 32t - 16t^2 ... How many seconds will it take before the object hits the ground?

Answer 1

Solve h = 0.

Answer 2

It should make sense that there are two values of t for this answer. It started at the ground when you threw it and then ended up on the ground later. check to see that this matches your answer as well jeremy.

Answer 3

So would I have 0=32t-16t^2
?

Answer 4

Then have 0 and 2 for x?

Answer 5

Yep exactly.

Answer 6

For t, I hope. Where did x come from?
