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
