Try the simplest way!

A particle moving along a straight line has a velocity v m/s, when it cleared a distance of x meters. These two are connected by the relation V = 49 + x V= \sqrt{ 49 + x } m/s. When its velocity is 1m/s its acceleration is "a". Find "10a " (assume uniform acceleration)


The answer is 5.

There are more than one way to solve this problem. I'll post the easiest one . On comparing the given relation with the third equation of motion i.e. v 2 = u 2 + 2 a s v^{2}= u^{2} + 2as Hence 2a = 1 or 10a = 5
