18. A 0.060-kg tennis ball, initially moving at a speed of 12 m/s, is struck by a racket causing i to rebound in the opposite direction at a speed of 18 m/s. What is the change in momentum of the ball? A) 0.36 kg-m/s B) 0.72 kg-m/s C) 1.1 kg-m/s 1.8 kg-m/s ? 1s 0.060-12= 02.?0.04 18 0.06*18-
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.
I git the answer to be A but I am unsure will someone double check?
