A particle is fired vertically upwards and its height, h metres, after any number of seconds, t, is given by formula h=50t-2t2 a) Find the height of particle after 2.3 seconds b) Find the speed of particle after 2.7 seconds c) What does dh/dt=0 mean in the context of the question? d) After how many seconds does the particle stop rising?
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.
