A tennis player tosses a tennis ball straight up and then catches it after 2.05 s at the same height as the point of release. (a) What is the acceleration of the ball while it is in flight? magnitude m/s² direction ---Select--- (b) What is the velocity of the ball when it reaches its maximum height? magnitude m/s direction Select--- (c) Find the initial velocity of the ball. m/s upward (d) Find the maximum height it reaches. m
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.
