In the Soapbox Derby in (Figure 1), young participants build non-motorized cars with very low-friction wheels. Cars race by rolling down a hill. Assume that the track begins with a 63-ft-long (1 m = 3.28 ft) section tilted 15 ∘ below horizontal. Part A: What is the maximum possible acceleration of a car moving down this stretch of track? Express your answer to two significant figures and include the appropriate units. Part B:If a car starts from rest and undergoes this acceleration for the full l, what is its final speed in m/s ? Express your answer using two significant figures
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.
