you arrive at the gates and you see your friend has already arrived. he is 125m ahead of you walking at a pace of 1.30m/s. You yell out to him but he doesn’t hear you so you must catch up to him. a) if you start to run towards your friends at a speed of 1.80m/s how long will it take to catch up to your friend? b) if you start to accelerate at a rate of 0.230m/s^2 from rest how long will it take you to reach a speed of 3.20m/s c) if you accelerate at a rate of 0.230m/s^2 until you reach a speed of 3.20m/s^2 and then travel there at that speed until you catch up to your friend how long in total will it take to catch up to your friend?

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.
