- Does a ruler balance exactly at its midpoint? What does this imply about the mass distribution of the ruler?I keep getting wrong answers for this problem how do I do it? solving for angular acceleration17. A tennis player's elbow is fully extended during impact with the ball. This is beneficial compared to a partially bent elbow because. the torque due to gravity will be increased i the linear velocity of the racquet head will be higher as long as the angular velocity is also high the coefficient of restitution will be greater the angular inertia of the racquet will be decreased allowing for a greater angular acceleration 18. A large spin is put on a jump serve in volleyball to accelerate the ball downwards once it passes the net. The topspin can be maximized by creating a greater torque with a force on the bottom of the ball contact the ball at a greater height from the ground hit with a greater force directed through the It's center generating a large torque onto the ball with frictional forces during contact
