A bead is moving with a speed of 20 m/s at position A on the track shown in the figure.

This track is friction - free, and there is no appreciable air resistance. What is the speed of the bead at point C?

Physics is present in the flight of the ball, the motion of the players, and the force of the tackles. This web page will show you how physics applies to these areas of football. When you throw a football across the yard to your friend, you are using physics. You make adjustments for all the factors, such as distance, wind and the weight of the ball. The farther away your friend is, the harder you have to throw the ball.

velocity or speed at which the ball leaves his foot * the angle of the kick * the rotation of the football

A 4.0 kg mass is moving with a speed of 2.0 m/s. A 1.0 kg mass is moving with a speed of 4.0 m/s. Both objects encounter the same constant braking force and are brought to rest. Which object travels the greatest distance before stopping?
