To determine the height of the object after a certain time it is dropped, we simply substitute the time to the function given. We calculate as follows:
h = -16t^2 + 1454
h = -16(8^2) + 1454
h = 430 feet above the ground
Hope this answers the question. Have a nice day.

Answer:
4π in ≈ 12.57 in
Step-by-step explanation:
One full revolution (2π radians) is made in 60 minutes. In 40 minutes, the hand moves through an angle θ of (40/60)(2π) = 4π/3 radians. The length of the arc is ...
s = rθ = (3 in)(4π/3) = 4π in ≈ 12.57 in
