    A ball of mass m is released from rest at a distance h above a frictionless plane inclined at an angle of 45° to the horizontal as shown above. The ball bounces elastically off the plane at point P1 and strikes the plane again at point P2. In terms of g and h determine each of the following quantities: a. The velocity (a vector) of the ball just after it first bounces off the plane at P1. b. The time the ball is in flight between points P1 and P2.

    hit a lightweight ball back and forth using table tennis rackets. The game takes place on a hard table divided by a net. Except for the initial serve‚ players must allow a ball played toward them only one bounce on their side of the table and must return it so that it bounces on the opposite side. Points are scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions. A skilled player can impart several varieties of spin to the ball‚ altering its trajectory

    dropped a racquetball from a height of one meter and measured the height at which the ball bounced back up from the ground. These values were used to find the total mechanical energy that was lost. In order to calculate the theoretical potential energy of an object‚ we shot a “superball” from a ballistic launcher at three different settings and measured the height the ball traveled as well as the velocity of the ball when it left the launcher. Using the values of the velocities at different settings

    track‚ this basket retained its bottom‚ and balls had to be retrieved manually after each "basket" or point scored Basketball was originally played with a soccer ball. The first balls made specifically for basketball were brown. Dribbling was not part of the original game except for the "bounce pass" to teammates. Passing the ball was the primary means of ball movement. Dribbling was eventually introduced but limited by the asymmetric shape of early balls. Dribbling only became a major part of the

This now replaced ones hand with a more effective way to hit and serve the ball‚ and so the first “racquet” was created.  With a new way to hit the tennis balls‚ then the ball went under reconstruction and redesign seeing as the first tennis ball was wooden. Soon the new ball was bouncier‚ it was made of leather filled with cellulose material. The game of

    because of Newton’s 3rd law. Applying more force in turn increases the base-runner’s velocity. Catching: When catching a fly ball or grounder‚ it is best to move with the ball and not catch it right over your head or right in front of you with stiff hands. By Newton’s 3rd law‚ for every action there is an opposite reaction‚ so we can decrease the amount of bounce the ball has on our hands. This is done by increasing the impact time. By increasing the impact time‚ we decrease the force making catching
