Question

The displacements of a particle at time t seconds is given by s=t(1-3) then find the velocity of the
particle at 1 =2sec​

Answer 1

Answer:

The displacement 's' of a particle at time 't' seconds is given by

(t−3)

−3t

We know that,

Velocity of a particle of displacement 's' at time 't' is given by

So,

Velocity is

Displacement :-

Its a vector quantity and is defined as shortest distance of the object between initial position and final position.

Velocity :-

It is a vector quantity which is defined as the rate at which position of the object changes.

Acceleration :-

It is a vector quantity and is defined as the rate at which Velocity of the object changes.
