Statement of a problem № m101437



Use the following differential equations to compute the velocity and position of a soccer ball that is kicked straight up in the air with an initial velocity of 40 m/s: Where y = upward distance (m), t = time (s), y = upward velocity (m/s), g = gravitational constant (= 9.81 m/s2), cd = drag coefficient (kg/m), and m = mass (kg). Note that the drag coefficient is related to more fundamental parameters by Cd = ½ pACd Where r = air density (kg/m3), A = area (m2), and Cd = the dimensionless drag coefficient. Use the following parameter values for your calculation: d = 22 cm, m = 0.4 kg, r = 1.3 kg/m3 and Cd = 0.52.
