d = 16t2 (d in ft, t in sec)
Set d = 75 ft and solve for t.
75 = 16t2
t = √(75/16) sec ≅ 2.17 sec
It hits the water in 2.17 sec.

Plug t=2 into d=16t^2.

If t is equal to 2, then it is the variable that is raised to the second power not the whole term. So then 2 raised to the second power is equal to four. 16 multiplied by 4 equals 64. Therefore it does fall to the ground in 2 seconds

Also, there is no variable d in the problem so you shouldn't include it in the solving. Remember, you're showing this to a kid so they know how to solve a problem similar to it, so make it simple for a kid to comprehend.
