Multiply the time, in seconds, by 32-1/6, and it will give the velocity
acquired in feet, per second.
_Example._ Required the velocity in seven seconds.
32-1/6 × 7 = 225-1/6 feet. Ans.
2.—_To find the Velocity a Body will acquire by falling from any given
height._
Multiply the space, in feet, by 64-1/3, the square root of the product
will be the velocity acquired, in feet, per second.
_Example._ Required the velocity which a ball has acquired in
descending through 201 feet.
64-1/3 × 201 = 12931; √12931 = 113·7 feet. Ans.
