Question

a man start walking and cover 3 meters in north direction then he turn right and cover 4 metre. from this point again he walks north direction and covered 3 meters distance then he take another right and cover 4 metre distance

find the total distance travel and total displacement​

Answer 1

nition of Equations of Motion

Equations of motion, in physics, are defined as equations that describe the behaviour of a physical system in terms of its motion as a function of time.

There are three equations of motion that can be used to derive components such as displacement(s), velocity (initial and final), time(t) and acceleration(a). The following are the three equation of motion:

First Equation of Motion : v=u+at

Second Equation of Motion : s=ut+12at2

Third Equation of Motion : v2=u2+2as

To brush up on the basics of motion, refer the article listed below::

Derivation of Equation of Motion

The equations of motion can be derived using the following methods:

Derivation of equations of motion by Simple Algebraic Method

Derivation of equations of Motion by Graphical Method

Derivation equations of Motion by Calculus Method

In the next few sections, the equations of motion are derived by all the three methods in a simple and easy to understand way.

Derivation of First Equation of Motion

For the derivation, let us consider a body moving in a straight line with uniform acceleration. Then, let the initial velocity be u, acceleration is denoted as a, time period is denoted as t, velocity is denoted as v, and the distance travelled is denoted as s.

Derivation of First Equation of Motion by Algebraic Method

We know that the acceleration of the body is defined as the rate of change of velocity.

Mathematically, acceleration is represented as follows:

a=
