The case where the rocket has alinear air drag force F= cV , where c is a constant. Assumingno burnout, solve for ω ( t ) and find the terminal angularvelocity—that is, the final motion when the angular accelerationis zero. Apply to the case M 0 = 6 kg, R = 3 m, m =0.05 kg/s, V e = 1100 m/s, and c = 0.075 N ? s/m to find theangular velocity after 12 s of burning.
The Air Force's new experimental jet, the X - 9001, is a perfectly flat, rectangular wing. It has a cruising speed of
100 m s¹. Determine the thrust force required to maintain that speed [36 N]. Neglect any frontal area or pressure
drag. Drag occurs on both the top and bottom of the plate. The plane may be considered to be 1 m long and 1 m wide.
