3- A man walks on a straight road from his home to a market 2.5 km away with a speed of 5 km/hr. Finding the market closed, he instantly turns and walks back home with a speed of 7.5 km/hr. Find The average speed of the man over the interval of time o to 40 min. 4- The motion of a particle is described by the equation x = a + bt? where a =15cm and b = 3cm. find the velocity at time 3 sec. 5- The displacement of the particle is given by y= a + bt + ct? - dt'. Find the initial velocity and acceleration.
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.
