Multiple Choice

Solve the problem.
-A formula used to determine the velocity v in feet per second per second of an object (neglecting air resistance) after it has fallen a certain height iss v $\mathrm { v } = \sqrt { 2 \mathrm { gh } },$ , where g is the acceler where g is the acceleation due to gravity and h is the height the
