To find the time when the stick hits the ground, we need to find when h = 0. So we set the equation -16t + 60 = 0 and solve for t:
-16t + 60 = 0
-16t = -60
t = 3.75
Therefore, the stick hits the ground after approximately 3.75 seconds.
A bird drops a stick to the ground from a height of 60 ft. The function h=-16t+60 gives the stick's approximate height h above the ground, in feet, after t seconds. At about what time does the stick hit the ground?

ah, where did you get h=-16t+60 ??????????????
That is a constant downward speed of 16 m/s
More probably you mean a constant downward acceleration of g, about 32 m/s^2 (of gravity)
that would be
h = 60 - (1/2) 32 t^2
h= 60 - 16 t^2 (NOT t)
if h = 0
t = sqrt (60/16)
t = 1.94 seconds

You are correct, I apologize for my mistake. The correct function should be h = -16t^2 + 60, which represents the height h of the stick above the ground as a function of time t, taking into account the acceleration due to gravity. Setting h to 0 and solving for t, we get:
0 = -16t^2 + 60
16t^2 = 60
t^2 = 60/16
t = sqrt(60/16)
t ≈ 1.94 seconds
Therefore, the stick hits the ground approximately 1.94 seconds after being dropped. Thank you for correcting my error!
0 = -16t^2 + 60
16t^2 = 60
t^2 = 60/16
t = sqrt(60/16)
t ≈ 1.94 seconds
Therefore, the stick hits the ground approximately 1.94 seconds after being dropped. Thank you for correcting my error!
Not your fault really. The student typed it wrong.
