A grab driver is traveling at 15 m/s when the traffic light 787 ft ahead suddenly turns red. The duration of the red light is 0.4 min. Determine the following: a) the required uniform deceleration in m/s of the motorcycle if
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.

ahead suddenly turns red. The duration of the red light is 0.4
min.
Determine the following:
a) the required uniform deceleration in m/s² of the motorcycle if
the driver intends to pass the light without stopping just as it
turns green again (report the final answer in 3 significant digits)
b) the velocity in km/hr of the motorcycle as it passess the light
(report the final answer in 3 significant digits)
