Hints About the Introductory Mechanics Unit
Speed and Position of an Aircart
Here, kinetic energy, hence the square of the speed, is proportional to
the work done by the propeller. Assuming a constant total force, this energy
is proportional to the distance travelled. Thus, the square of the speed
is proportional to the distance travelled and the ratio of squared Speed
to Distance is twice the ratio of Force and Mass.
Fs=.5mv*v => v*v/s = 2F/m
