A toy rocket is launched from the top of a building 150 feet tall
at an initial velocity of 213 feet per second.
a) Give the function that describes the height of the rocket in
terms of time t
b) Determine the time at which the rocket reaches its
maximum height, and the maximum height in feet.
c) For what time interval will the rocket be more than 831 feet
above ground level?
d) After how many seconds will it hit the ground?
www
terms of t is s(t)= - 16t² +213t+150
b) The rocket reaches its maximum height of 858.890 feet
after approximately 6.66 seconds.
(Round to the nearest hundredth as needed.)
c) The rocket will be more than 831 feet above ground level
for all values of t in the interval
(Type your answer in interval notation. Do not round until
the final answer. Then round to the nearest hundredth as
needed.)
