Drop a 4451 lb flat plate (area = 15444.5 sq inches) which stays flat while falling from 1 mile high. How much HP needed for a car to drive past impact point starting at zero and 1 mile from impact point? Known factors: Coefficent of drag C(d)= 1.28 , Air Density (no wind) p = .002377slugs per ft cubed. Gravity constant =g=32.2ft/sec squared, Horsepower needed to accelerate is AVERAGE - not peak

A 600-g squirrel with a surface area of 935 cm2 falls from a 5.6-m tree to the ground. Estimate its terminal velocity. (Use the drag coefficient for a horizontal skydiver. Assume that the cross-sectional area of the squirrel can be approximated as a rectangle of width 11.6 cm and length 23.2 cm. Note, the squirrel may not reach terminal velocity by the time it hits the ground. Give the squirrel's terminal velocity, not it's velocity as it hits the ground.)...
