1. Car A is moving with a constant velocity 5.57 while Car B starts from rest and accelerates with a constant acceleration 2.93. They both start at the same position. How long in seconds before Car B overtake Car A?
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.

2. A ball is thrown upwards with an initial velocity of 8.71 m/s. How long in seconds does it take before the ball goes back to its initial position?
3. A projectile is fired at the edge of a cliff, with initial an velocity of 12m/s at an angle of 40 degrees. If it takes the projectile 10s to land on the bottom of the cliff, how high is the cliff?
