A freely falling bowling ball lands on the ground 2.7 s after being thrown. With what velocity and from what height was the ball thrown? Assume one-dimensional motion and for directions use + for up and - for down. Hint: solve symbolically for the initial velocity in terms of the height and plug in each height below to see which matches its corresponding velocity. O -2.3 m/s, 34 m O 3.1 m/s, 47 m O 3.5 m/s, 42 m O 3.5 m/s, 47 m O 2.3 m/s, 42 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.
