2) You have been contracted by Boba Fett who regularly has to jump off a 100m platform wearing a rocket powered jet backpack. Boba Fett has a healthy mass of 100kg and knows no fear. The jetpack has an empty mass of 20kg including the propellant tank. The thruster for the backpack delivers an Isp of 200 sec (U₂ = 1960 m/sec). If he is given 4kg of propellant, at what height must he turn on the thruster such that he lands with zero velocity and uses all his propellant? There are multiple approaches and solutions to this problem, e.g. vis viva equation or direct kinematics. Boba can withstand a maximum limit of 4gees (not a hard constraint that he has to endure 4gees, just ensure he never exceeds that threshold). Gravity should be assumed Earth-normal (i.e. g. = 9.807 m/s²) and you may ignore drag and ignore fear.
