If a man ran @ 3m/s for 10s and then -3m/s for 10s more.... A.What is the distance traveled? B. Average speed ? C. Displacement @ end of trip ? D. Average velocity and direction if any ? Can you show me how to solve this please. Thanks
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.
Concept
Scalar and vector quantities.
Scalar quatities are independent of direction whereas the vector quantities depends on the direction.
Distance and speed are scalar quantities.
Displacement and velocity are vector quantities.
Given
Man ran at 3m/s for 10s and then -3m/s for 10s more.
