Solve the problem.When an object is dropped to the ground from a height of h meters, the time it takes for the object to reach the ground is given by the equation t = 
, where t is measured in seconds. Solve the equation for h. Use the result to determine the height from which an object was dropped if it hits the ground after falling for 3 seconds.
A. h = 4.9t; 14.7 m B. h = 4.9t2; 44.1 m C. h = 24.01t2; 216.1 m D. h = 24.01t; 72 m
