Define Rocket in Drag (Princeton)?
A rocket has an effectual frontal area A and blasts off with a constant acceleration a straight up from the surface of the Earth.
a) Use either/or dimensional analysis or an elementary derivation to find out how the atmospheric drag on the rocket should vary as some power(s) of the area A, the rocket velocity v and the atmospheric density p assuming that we are in the region of high Reynolds numbers.
b) Presume that the atmosphere is isothermal with temperature T. Analyzes the variation of the atmospheric density p with height z. Presume that the gravitational acceleration g is a constant and that the density at sea level is Po.
c) Find the height ho at which the drag on the rocket is at an utmost.
A car of mass 1600 kilograms (kg) was travelling at 30m/s when the brakes were applied and produced a constant retarding force of 8000 N (Newtons) to the car: Find - a) How far the

pseudo force: A "force" that arises since an observer is naively treating an accelerating frame like an inertial one.
