▼ Part A Your friend, who in a field 70 meters away from you, kicks a ball towards you with an initial velocity of 20 m/s. Assuming the grass causes the ball to decelerate at a constant rate of 1.0 m/s², how long does it take for the ball to reach you? Express your answer with the appropriate units. t= 100 3 · S C ?
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.
