*Problem 4: т A car is moving with an initial velocity vo = 26 £– at an initial position of 7, =-10 £ m. The driver sees a stop m sign 50 m ahead. The car has a maximum braking acceleration of ả = -5£ . a) Find the time required for the car to stop. (A: 5.2(s)) b) Find the final position of the car. Did the car stop before the stop sign? (A: 57.4(m))
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.
