Skid marks at the scene of an accident indicate that a car took 55 m to stop. Assuming that the car slowed down uniformly at a rate of 8.0 m/s2, answer the following questions: a) How fast was the car going before it started to stop? Report your final answer in miles/hour. b) How long did it take the car to come to a stop? Report your answer in seconds. Please provide work :)
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.
