A "happy ball" was dropped from an initial height of 1m as it bounced back up to a maximum height of .58 meters. When a "sad ball" was dropped from an initial height of 1m, the ball didnt bounce. Both balls have a mass of 9.5 grams. Can you please help me calculate the velocity of the "happy ball" just before and after hitting the ground using kinematics equations? Thank you in advance.
