falling object like a parachutist with the following differential equation:

ππ£/ππ‘ = π -(ππ/π)*π£^2

where π£ is velocity (m/s), π‘ is time (s), π is the acceleration due to gravity (9.81 m/s^2), ππ is a

second-order drag coefficient (kg/m), and m is mass (kg). Solve for the velocity and distance

fallen by a 90 kg object with a drag coefficient of 0.225 kg/m. if the initial height is 1 km,

determine when it hits the ground. Obtain your solution with

(i) Eulerβs method

(ii) The fourth-order RK method
