A truck covers 45.0 m in 8.10 s while smoothly slowing down to final speed of 2.60 m/s. (a) Find its original speed. 6.57 The constant acceleration equation involving average velocity, + vyf) might be easiest to use here. m/s (b) Find its acceleration. (Indicate the direction of the acceleration with the sign of your answer.) -0.49 You appear to have correctly calculated the acceleration using your incorrect value from part (a). m/s?
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.
