Question

a particle is moving in a straight line from o to a with a constant acceleration of 2 metres per sec m. It velocity at A is 30 meters per sec and it takes 15 sec to travel from O to A. find the velocity at A brainly solution

Answer 1

Answer:

Velocity at A = 60 m/s

Explanation:

First of all, there is a BIG MISTAKE in your question!!!

Look at the second line: 'Its velocity at A is 30 m/s'. Now look at the question: 'Find the velocity at A' . Look, you have given the answer in the question already! So, I think you meant the question to be: 'Its velocity at O is 30 m/s'. I think you meant that and I'm proceeding my answer according to my assumption.

Velocity at O u = 30 m/s

Acceleration a = 2 m/s²

Time taken t = 15 s

According to the first equation of motion, v = u + at

v = 30 + 2 × 15 = 30 + 30 = 60 m/s

Hope this helps, if you meant the question I've given:/
