Explanation:

Kinematics is the branch of classical mechanics that describes the motion of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion. ... The movement is relative, that is, it will depend on the reference system we choose.

Kinematics Examples

Firing a cannonball.

Shooting a basketball

Kinematics, branch of physics and a subdivision of classical mechanics concerned with the geometrically possible motion of a body or system of bodies without consideration of the forces involved (i.e., causes and effects of the motions). ... In unconstrained, or free, motion, the forces determine the shape of the path.

Function

Kinematics aims to provide a description of the spatial position of bodies or systems of material particles, the rate at which the particles are moving (velocity), and the rate at which their velocity is changing (acceleration).

Variable

Kinematic variables allow the description of the motion of a body without reference to variables that act to change the motion of the body. (The variables that act to change the motion of a body, kinetic variables, will be covered elsewhere.)

Basics

Kinematics is the branch of mechanics concerned with the motions of objects without being concerned with the forces that cause the motion. ... There are three basic concepts in kinematics - speed, velocity and acceleration

Position

Kinematics involves position, velocity and acceleration (and their rotational equivalents). Position is the point in space that an object occupies, this needs to be defined in some coordinate system. Velocity is the rate of change of position with respect to time.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6 $\frac{m}{s^{2} }$

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
