Distance H in feet that an object falls in T seconds is modeled by the formula H equals 16 T2 squared if you drop a rock from a cliff 1960 above the water how long will it take the rock to hit the water

Answer:

after 11.07secs

Step-by-step explanation:

Given the height of an object modeled by the equation

H = 16T² - 1960

The height of the object on the surface of water is zero, hence H = 0

Substitute

0 =16T² - 1960

Swap

16T² - 1960 = 0

16T² = 1960

T² = 1960/16

T² = 122.5

T = 11.07

Hence the rock will hit the surface of the water after 11.07secs
