hm | 18ms B Figure 4 The fixed point A is h metres vertically above the point O that is on horizontal ground. At time t- 0, a particle P is projected from A with speed 10ms'. The particle moves freely under gravity. At time 1 = 2.5 seconds, P strikes the ground at the point B. At the instant when P strikes the ground, the speed of P is 18ms', as shown in Figure 4. (a) By considering energy, find the value of h. (b) Find the distance OB. As P moves from A to B, the speed of P is less than or equal to 8ms' for T seconds. (c) Find the value of T
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.
