Question

A body moving with uniform acceleration is having
velocity 2 m/s and 8 m/s at t = 1 s and t = 4 s
respectively. Then average velocity of particle in the
time interval t = 1 s to t = 4 s is
(2) 3 m/s
(1) 2 mts
(3) 5/3 m/s
(4) 5 m/s​

Answer 1

Answer:

The average velocity of the particle is 5 m/s.

(4) is correct option.

Solution:

To Find:

Average velocity of the particle.

Method:

According to your question,

Initial velocity :

Final velocity :

We have to caculate the average velocity of particle  if the acceleration is uniform.

We know that,

Average velocity :

Average velocity is equal to the sum of the initial and final velocity and divided by two.

Now,

Values will be after applying formula,

Hence,

The average velocity of the particle is 5 m/s.
