Answer 2

The velocity of the particle is 0.133 m/s

Given : The position of the particle going along a straight line is equal to 100 m at 10 a.m.

The position of the particle going along a straight line is equal to 200 m at 10.30 p.m.

To Find : Velocity of the particle

Solution : The velocity of the particle is 0.133 m/s

It is given that the  position of the particle going along a straight line is equal to 100 m (x1) at 10 a.m. and the position of the particle going along a straight line is equal to 200 m (x2)  at 10.30 p.m.

Velocity of the particle is defined as the

Velocity = $\frac{Displacement}{Time}$

Now as the particle position changes from x1 to x2 , so displacement is x2-x1  

= 200 -100 = 100 m

The particle position is equal to 100 m at 10 a.m. and the second position is equal to 200 m at 10.30 p.m. so total time is 12.5 hours which is equal to 750 seconds

So putting all the values in the above equation

velocity = $\frac{100}{750}$

= 0.133 m/s

So the velocity of the particle is 0.133 m/s
