Sitting at the edge of a cliff, you throw a stone vertically upward with a velocity of 30 m/s. The height of the stone above the cliff's edge in units of 10 meters can be approximated by
f(t) = 3t − 0.5t2.
(a) From the graph, at what time does the stone reach its highest point? (Round your answer to one decimal place.)
t = s
(b) How high above the cliff does the stone reach? (Round your answer to one decimal place.)
m
(c) When is the stone again at the elevation of the cliff's edge? (Round your answer to one decimal place.)
t = s
(d) You check your watch and observe that the stone hits the ground below the cliff after 7 seconds. How high is the cliff? (Round your answer to one decimal place.)
