Transcribed Image Text:A cliff diver plunges from a height of 12.1 m above the water surface. The distance the diver falls in t seconds is given by the function d(t) = 4.96² m.
Which equation can be solved for t to find the time (in seconds) when the diver hits the water?
4.9t² = 0
O 4.9²
12.10
O 4.9² - 12.1 12.1
Ⓒ4.9² - 12.1
=
O 4.9² +12.1= -12.1
After how many seconds will the diver hit the water? (Round your answer to one decimal place.)
Given that the velocity of the diver at time t = a is given by
