A stone is dropped from the upper observation deck of a tower, 150 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)-150-4.9² (b) How long does it take the stone to reach the ground? (Round your answer to two decimal places.) 5.53 S (c) with what velocity does it strike the ground? (Round your answer to one decimal place.) -54.2 m/s (d) If the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (Round your answer to two decimal places.) 5.14 A stone is dropped from the upper observation deck of a tower, 150 m above the ground. (Assume g -9.8 m/s².)
