Answer:

time = 2.48 seconds

Step-by-step explanation:

Given data:

distance = 100 foot

Initial velocity = 0 <em>because it was held and being released.</em>

acceleration is gravitational force

<em>gravitational force in feet per second = 32.2 ft/s²</em>

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

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)
