A stone is dropped from the upper observation deck of a tower,
100 m above the ground. (Assume g = 9.8 m/s2.)
(a) Find the distance (in meters) of the stone above ground
level at time t.
h(t) = −4.9t2+100
(b) How long does it take the stone to reach the ground?
(Round your answer to two decimal places.)
(c) With what velocity does it strike the ground? (Round your
answer to one decimal place.)
(d) If the stone is thrown downward with a speed of 6 m/s, how
long does it take to reach the ground? (Round your answer to two
decimal places.)
