blank 10ms 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.
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.
