A student is running at her top speed of 5.5 m/s to catch a Shuttle bus, which is stopped at the bus stop. When the student is still a distance 41.4 m from the Shuttle bus, it starts to pull away, moving with a constant acceleration of 0.177 m/s2 Part A For how much time does the student have to run at 5.5 m/s before she overtakes the bus? t= s Part B For what distance does the student have to run at 5.5 m/s before she overtakes the bus? d= m Part C When she reaches the bus, how fast is the bus traveling? v= m/s Part D What is the minimum speed the student must have to just catch up with the bus? v= m/s Part E For what time does she have to run in that case? t= s Part F For what distance does she have to run in that case? d= m
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.
