Need Help 2 problems!
Homework Problem 1:
You are starting out a race to go from point A to point B, and then
back. You have to stop on your return to point A. The initial mass
of your rocket is 80% fuel. Racer 1, who is not as smart as you
and is not taking this class, plans to use ¼ of the fuel to speed
up, ¼ of the fuel to come to a stop at point B, ¼ of the fuel to
speed back up, and the final ¼ of the fuel to stop at point A.
● A) You have a better strategy. What is it?
● B) Assuming the distance between A and B is long - you coast
most of the way - how much faster are you compared to racer
1?
● C) Does Racer 1 have enough fuel left to come to a stop at the
finish point A? If not, what is Racer 1's final speed (v/u). If so,
how much fuel is left over?
Homework Problem 2:
Assume an initial speed of 100 m/s, initial height of 100 m, and
work out the angle that gives the longest trajectory. Give the
angle as xx.xx degrees and the range (horizontal distance
traveled) as yyyy m. Do this numerically, on computer.
