For the following parts, use the fact that when an object is moving at constant velocity, position s and time t are related by s = vt + 80 , where v is the speed of the object and so is the position at time zero in the chosen coordinate system. Part B You wave goodbye to a friend after physics class, and she rides off on her bike. After 3.0 s, she is 15 m away. How far away will she be after 30 s ? Express your answer in meters to two significant figures. • View Available Hint(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.
