An egg is dropped from a height of 20 m. the egg is in free fall the entire time it falls. what willthe speed of the egg be when it lands after falling for 2 seconds?

This involves a kinematics equation for constant acceleration, which contains the variables of velocity initial, velocity final, time and acceleration: V final = V initial + AT
Acceleration = -9.8
V initial = 0
V final = ?
Time = 2
V final = 0 + (-9.8)(2)
V final = -19.6 m/s
