Homework Statement
An ideal parachute accelerates all the air it sweeps as it travels, and the air is accelerated from
0 to the parachute's velocity. Using F = dp/dt calculate the force on an ideal parachute of area A as a function of its velocity and the density of air. Assuming you wouldn't break any limbs if you jumped from 5 feet high without a parachute, this tells you what steady-state velocity you would like your parachute to reach. What diameter a circular parachute you would need? Suppose you weigh 100 kg (including the parachute, a spare, and a video camera to document your jump) and the air density is 1.2 kg/m^3
