when it hits the ground is when h=0, so you just need to sub. h=0 into the given equation and solve for t
0= -16tsquare + 100
cheers
The height of an object dropped from a 100-ft-tall building is given by h=-16t squared + 100. When will the object hit the ground? (Please provide steps/explanation to solve this problem.)
