Question: a. Rationalize the denominator in the expression t = -2d/a . b. Use the rationalized expression from part a. to calculate the time in seconds

a. Rationalize the denominator in the expression t = -2d/a .

b. Use the rationalized expression from part a. to calculate the time in seconds that a cliff diver is in free fall. Assume the acceleration due to gravity, a, is -9.81 m/s and the dive distance, d, is -35 m. The negative numbers indicate the direction is downward. Round the answer to two decimal places.

c. Use the formula v = -3.62ad to calculate the velocity of the diver in km/h when she or he hits the water. Round the answer to one decimal place.
