Question

Use the formula h=16t^2 to solve the problem . A diver dives from a cliff that has a height of 86.4 feet. Determine the time of the dive . Round answer to the nearest tenth of a second

Answer 1

2.3 seconds. Let's assign the known values to the equation and solve for t. h = 16t^2 86.4 = 16t^2 5.4 = t^2 2.323790008 = t Rounding to the nearest tenth of a second gives 2.3 seconds.
