**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.
