DIRECTIONS: Use this information to answer Parts A and B.

The time, t, in seconds that it takes an object to reach the ground when dropped from height, h, in meters is given by the formula t=(10h49)12.

Question 1
Part A

Which equation is equivalent to the given formula?


t=h7t is equal to h over 7

t=10h√7t is equal to the fraction with numerator square root of 10 h and denominator 7

t=100h98t is equal to 100 h over 98

t=4910h−−−√t is equal to square root of 49 over 10 h end root
Question 2
Part B

How many seconds will it take an object dropped from 19.6 meters to reach the ground?
