A stone is dropped from the upper observation deck of a tower, 150 m above the ground. (Assume g = 9.8 m/s.) (a) Find the initial values of the velocity v (in m/s) and the distance s (in meters) of the stone above the ground. v(0) = m/s s(0) = m Find the velocity (in m/s) of the stone at time t. v(t) = m/s Find the distance (in meters) of the stone above ground at time t. s(t) = m (b) How long (in seconds) does it take the stone to reach the ground? (Round your answer to two decimal places.) (c) With what velocity (in m/s) does it strike the ground? (Round your answer to one decimal place.) m/s (d) If the stone is thrown downward with a velocity of 4 m/s, how long (in seconds) does it take to reach the ground? (Round your answer to two decimal places.)
