Question: The height of a helicopter above the ground is given by h = 2.80t3, where h is in meters and t is in seconds. At t = 1.75 s, the helicopter releases a small mailbag.

Part A: How long after its release does the mailbag reach the ground?

I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
