1. A ball is thrown from a height of 4.3 m at an angle of 57° upwards from the horizontal with a speed of 17 m/s. Determine the following: a) What maximum height does it reach? b) How far does it travel horizontally from when it is thrown until it hits the ground? 57° c) What is its velocity (magnitude and direction) just before it hits the ground? 17 m/s, 4.3 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.
