A soft tennis ball is droppped onto a hard floor from a haight of 1.25m and rebounds to a height of 0.95m. For this problem use a coordinate plane in which up is positive. a. calculate the vertical component of it velocity in m/s just before it hits the floor b.calculate its velocity in m/s just after it leaves the floor on its way back up c.calculate its avg. acceleration in m/s2 during contact with the floor if that contact lasts 3.50 x 10-3 s d. how much did the ball compress in meters during its collision with the floor assuming the floor is absolutely rigid
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.
