While driving along the highway at 40 m/s, you spot a police car 50 m ahead, traveling at a constant speed of 25 m/s which is the speed limit. You apply brakes and begin decelerating at 1.5 m/s?. A. Determine the time/s that you and the police will pass each others car. B. Assume that the police will give speeding ticket at the first instance that you passed each others car, will you get a ticket? If you WILL get a speeding ticket, what should be your acceleration to avoid the speeding ticket? If NOT, what was your instantaneous velocity as you passed the police car? C. If the police missed to check your speed at the first instance that you passed each other's car, will you be getting the a speeding ticket at the next instance? Justify your answer numerically.

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.
