Part 1: A motorist traveling at 17 m per s encounters a deer in the road 48 m ahead. If the maximum acceleration the vehicle's brakes are capable of is -5 m per s2 what is the maximum reaction time of the motorist that will allow her or him to avoid hitting the deer? Answer in units of s. Part 2: If his or her reaction time is 1.29353s, how fast will (s) he be traveling when(s)he reaches the deer? Answer in units of m per 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.
