A car travels at 35.0 mph for 0.5 hours, at 65.0 mph for the next 2.5 hours and finally at 80.0 mph for 1.5 hours. The car's average velocity for the entire journey was around 80 mph None of these are correct 180 mph 60 mph 67 mph
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.
Average velocity is calculated by the formula,
V = S/t
S = V×t
Where, V equals the average velocity, S equals total displacement and t equals total time.
Given,
Velocity, V1 = 35 mph
Time, t1 = 0.5 h
Velocity, V2 = 65 mph
Time, t2 = 2.5 h
Velocity, V3 = 80 mph
Time, t3 = 1.5 h
