Identify each problem as type: ”Given location, ﬁnd slope,” or: ”Given slope, ﬁnd location.”
Then solve each problem.
1. An object is dropped from a tower so that after t seconds its height above ground is h(t) =
100 − 16t2 feet.
(a) What is its velocity after 2 seconds?
(b) When is its velocity −60 ft/s?
(c) What is its velocity at the time when it hits the ground?
(d) How high is it when its velocity is −48 ft/s?
