To find velocity in feet per second of a falling body, given the time of
fall in seconds.
Set index on C to time of fall on D, and under 32·2 on C read velocity
in feet per second on D.
To find velocity in feet per second, given distance fallen through in
feet.
Set 1 on C to distance fallen through on A, and under 64·4 on B read
velocity in feet per second on D.
EX.—Find velocity acquired by falling through 14 ft.
Set (R.H.) index of C to 14 on A, and under 64·4 on B read 30 ft. per
second on D.
To find distance fallen through in feet in a given time.
Set index of C to time in seconds on D, and over 16·1 on B read distance
fallen through in feet on A.
