Times New. 2. 4. 5. 6. Problem 4: Two cars are in a 500 meter race. Car 1 has an acceleration of 3 meters per second squared, and a maximum velocity of 54 m/s. Car 2 has an acceleration of 4 meters per second squared, with a maximum velocity of only 45 m/s. Assume that the cars are able to move with their maximum acceleration up until they reach their maximum velocity, then stop accelerating. If both cars start at the same time, which car passes the finish line first? (HINT: Consider first how long it takes each car to reach its maximum velocity, and how far it travels during that time. Then consider how long it takes to travel the remaining distance at its top speed.)

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.

Problem 4: Two cars are in a 500 meter race. Car 1 has an acceleration of 3 meters per second
squared, and a maximum velocity of 54 m/s. Car 2 has an acceleration of 4 meters per second
squared, with a maximum velocity of only 45 m/s. Assume that the cars are able to move with
their maximum acceleration up until they reach their maximum velocity, then stop accelerating.
If both cars start at the same time, which car passes the finish line first?
(HINT: Consider first how long it takes each car to reach its maximum velocity, and how far
it travels during that time. Then consider how long it takes to travel the remaining distance at
