Use bisection to determine the drag coefficient needed so that a 65kg bungee jumper has a velocity of 35m/s after 4.5s of free fall. Note: The acceleration of gravity is 9.81m/s2. Start with initial guesses of xl= 0.2 and xu= 0.3 and iterate until the approximate relative error falls below 2%.

Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4×10 to the power of 23 kg, radius = 3.4×10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3×10 to the power of 8 km from the sun.)
