A bicyclist accelerates at a constant rate from a standstill to 20 km/hr in 36 sec. a) How fast is the bicyclist traveling after 10 sec? b) How far has the bicyclist traveled after 36 sec? a) After 10 sec, the bicyclist is traveling km/hr. (Round to two decimal places as needed.) b) After 36 sec, the bicyclist has traveled km. (Round to four decimal places as needed.)
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.
