Question

A vehicle moving with uniform acceleration of 2m/s has a velocity of 4m/s at a certain time

Answer 1

Hello friend
-----------------

As we all know that velocity means the distance traveled by an object in particular direction in unit time.

In your example the following values are given.

Given:

Acceleration,a = 2 m/s

Initial Velocity,u = 4 m/s.

( Initial velocity we have taken because the work is not completed means the work is in progress)

So,by using the first equation of motion.

we get,

v = u + at

So,if we consider the time as 5s.

Means Time,t = 5s.

Then we can find the final velocity of the vehicle.

So,

v = u + at

v = 4 + 2*5

v = 4 + 10

v = 14 m/s.

So, the final velocity of the object is 14m/s.


You can solve more examples if you know the time or you can consider the different values of time to solve this equation.

.....I hope this will helps you

Thanks.
