Amir starts riding his bike up a 200-m-long slope at a speed of 12 km/h, decelerating at 0.20 m/s as he goes up. At the same instant, Becky starts down from the top at a speed of 6.0 km/h, accelerating at 0.80 m/s? as she goes down. Part A How far has Amir ridden when they pass? Express your answer with the appropriate units.
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.
Given data:
Length of ride (L) = 200 m
Speed of the bike (v) = 12 km/h
=12*5/18 = 3.33 m/s
De-acceleration of the bike (a) = -0.2 m/s2
Speed of the Becky starts from the top (V) = 6 km/h
= 6*5/18 = 1.67 m/s
The acceleration of Becky is (a) =0.8 m/s2
Need to determine the distance of Amir when they both pass to each other.
