Alexis moves with a constant speed of 1.40 m/s and passes an apartment building in a moment. Lourdes finds herself in front of a church and bikes out to meet Alexis just as he passes the apartment building. If the magnitude of Lourdes' acceleration is 0.125 m/s2 and the building is separated from the church by a distance ? = 400 m, calculate: a) How long does Alexis take to meet Lourdes? And How far does each of them travel until they meet? b) What speed is Alexis traveling when he meets Lourdes? And What speed is Lourdes traveling when she meets Alexis? c) Explain with arguments, which of the two will reach the other building first?
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.
