An object is released from rest near and above Earth’s surface from a distance of 10m. After applying the appropriate kinematic equation, a student predicts that it will take 1.43s for the object to reach the ground with a speed of 14.3m/s . After performing the experiment, it is found that the object reaches the ground after a time of 3.2s. What is the final speed of the ball? Assume that the acceleration of the object is constant as it falls.
