A child running in a field has the following position and velocity at time t=0: x = 1.5 m. v= -2.0 m. Vx =-3.5 m/s, vy = 1.0 m/s At time t = 2.5 s, it has the following position and velocitv
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.
A child running in a field has the following position and velocity at time t=0: x = 1.5 m. v= -2.0 m. Vx =-3.5 m/s, vy = 1.0 m/s
At time t = 2.5 s, it has the following position and velocitv: x = -1.0 m, y = 1.5 m 08. Vx = -0.50 m/s, Vy = 2.0 m/s Using this information, find the magnitude and direction of the child's
a) average velocity during that time interval, and
b) average acceleration during that time interval.
Given,
At t=0
x = 1.5 m , y= -2.0m
vx =-3.5 m/s, vx = 1.0 m/s
At t=2.5sec
x= -1.0m , y= 1.5m
vx= -0.50m/s , vy= 2m/s u
