Suppose you throw someone a ball, thereby transporting kinetic energy. Could you consider the motion of the ball to be a mechanical wave ?

When speed of the ball is doubled its kinetic energy is

As you throw a heavy ball upward, is there any change in the normal force on your feet?

An out fielder throws a cricket ball with an initial kinetic energy of 800 J and an nfielder catches the ball when its kinetic energy is 600J . If the path of the bal between them is assumed straight and is 20m long, the air resistance acting on the ball is

During elastic collision of two balls, is kinetic energy conserved during the short interval of contact of balls ?
