![fill the tanks for two and a half hours. Calculate how many tons of fuel are in the
and t is measured in hours. They
tanks once they are full, rounded to the nearest ton.
2) You know the Excelsior must achieve 30,000 mph to reach escape velocity. The
rocket's engines are state-of-the-art and capable of creating an acceleration based
on the profile a=10t, where t is in seconds and a is in 2. Unfortunately the pull
of gravity works against the'rocket's motion at 32 ,2. Neglecting wind
resistance, calculate how long to burn the fuel to allow the Excelsior to achieve
30,000 mph, rounded to the nearest minute.
3)
The straight-line distance from Earth
Mars at the time the launch is scheduled is
100 million miles. In order to avoid other celestial bodies the Excelsior must travel
in an arc given by the equation y = -
(x-50)2+20, where x and y are in
125
millions of miles, and the x-axis denotes the straight-line distance to Mars. Find
the actual distance travelled by the Excelsior rounded to the nearest million and
then find the approximate time for the trip rounded to the nearest month,
assuming a constant speed of 30,000 mph and 30 days in each month.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4a68abd6-3d28-4a78-85a0-14a46a1e6728%2F348059a0-0f83-4847-8c16-ac6ce384d79a%2Fgmg042q_processed.jpeg&w=3840&q=75)
