A tennis ball with a speed of 13m/s is moving perpendicular to a wall. After striking the wall,the ball rebounds in the opposite direction with the speed of 7.839m/s. If the ball is in contact with the wall foe 0.0113s,what is the average acceleration of the ball while it is in contact with the wall? Take toward the wall to be the positive direction. Answer in units of m/s*2
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
