(b) Which of the following graphs describe an object motion with constant acceleration. Explain why. x(m) t(s) TWN vim/s) (1) t(s) a(m/s) t(s) (e) A racing car can travel a straight line from a dead stop to 48.3 km/h in 3.80 seconds. It takes an additional 3 seconds to reach 80.5 km/h and 16.7 more seconds to attain 161 km/h. What is the magnitude of its average acceleration in m/s² during each of these intervals?
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.
