Question

The velocity is equal to the rate of change of distance x(m):

dx/dt = v(t)....................(1)
dv/gt = g - (C????/m) ⋅ v²....(2)

Use Euler's method the numerically integrate equations (1) and (2) in order to determine both velocity and distance fallen as a function of time for the first ten seconds.

Answer 1

the question continues with other details ; Assume mass = 68.1Kg, drag coefficient c = 12.5kg/s and obviously g = 9.81m/s2.

Distance ( X) = 17.42M

Velocity V(t) = 16.42m/s
