Question
ustatic=0.768. A volleyball player is wearing a pair of the shoes tested in question #1 as she plays a game on a wooden gym floor. While jumping for a block, the component of force that she exerts perpendicular to the ground is 1656 N, spread out evenly between her two feet. If the coefficient of friction is the same as in the test above, what is the maximum frictional force (Ff) that she can exert on the ground with one of her feet, without slipping
ANS: 0.768*1656N=1272 N
Later in the game, while chasing the ball, the player from question #2 is exerting a vertical force of 1480 N and a horizontal applied force of 920 N on the ground with her left foot (for this particular instant in time, her right foot is not in contact with the ground because she is running). Will she slip? Explain why or why not
Explanation / Answer
Player will not slip.
Maximum frictional force it can exert = 0.768*1480 = 1136.64 N
Since 920 < 1136.64, so player will not slip.
