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.
i need help solving for average speed please
Given data:
The total distance is s = 100 mi
Half the distance ( s1 ) to the house has been traveled by the speed v1 = 32 mph
Rest half the distance ( s2 ) to the house has been traveled by the speed v2 = 68 mph
Consider the time taken for the first half is t1 and for the second half is t2 .
