If the object hit the ground, then this mean that the height is 0, right?
so solve for it like this:
0= -16t^2+144
-144 = -16t^2
Divide by (-16)
9= t^2
square root both sides
t= 3 or -3
there is no negative time then the object will hit the ground after 3 secs
Answer:
62.5%
Step-by-step explanation:
(56 - 62) / 4 = -1.5 z score = 0.0668
