How long would it take for a ball dropped from the top of a 100-foot building to hit the ground? Round your answer to two decimal places.

time = 2.48 seconds

Step-by-step explanation:

Given dа ta:

distance = 100 foot

Initial velocity = 0 because it was held and being released.

acceleration is gravitational force

gravitational force in feet per second = 32.2 ft/s²

formula for distance is s = ut + (1/2) at² where s = distance, u = intial velocity, a = acceleration and t = time

s = ut + (1/2) at²

100 = 0 (t) + (1/2) (32.2) t²

100 = 16.2t²

100/16.2 = t²

therefore t = 2.484

t = 2.48 seconds (to 2 decimal places)
