A car is parked on a steep incline overlooking the ocean, where the incline makes an angle of 50 with the horizontal. The parking brakes are defective. The car rolls from rest down the incline 50 to the edge of a cliff, when it reaches the cliff the velocity was 30 m/s: the hieght if the cliff 40m a. Find the acceleration of the car when it reaches the cliff b. The velocity of the car when it lands in the ocean c. The total time the car is in motion d. The position of the car relative to the base of the cliff when the car lands in the ocean.
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.
