Tiffany is a model rocket enthusiast. She has been working on a pressurized rocket
filled with nitrous oxide. According to her design, if the atmospheric pressure exerted
on the rocket is less than 10 pounds/sq. in., the nitrous oxide chamber inside the rocket
will explode. Tiff worked from a formula
/10 14.7 h
p e
pounds/sq. in. for the
atmospheric pressure h miles above sea level. Assume that the rocket is launched at
an angle of α above level ground at sea level with an initial speed of 1400 feet/sec.
Also, assume the height (in feet) of the rocket at time t seconds is given by the
equation
2
y t t t 16 1400sin . [UW]
a. At what altitude will the rocket explode?
b. If the angle of launch is α = 12°, determine the minimum atmospheric pressure
exerted on the rocket during its flight. Will the rocket explode in midair?
c. If the angle of launch is α = 82°, determine the minimum atmospheric pressure
exerted on the rocket during its flight. Will the rocket explode in midair?
d. Find the largest launch angle α so that the rocket will not explode.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
