Sometime we have seen that the solving values of x does not satisfy the given conditon, so we reject those values.
A particle possess two velocities simultaneously at an angle of ; to each other. Their resultant is 15 m/s. If one velocity is 13 m/s, then the other will be :
5 m/s
4 m/s
12 m/s
13 m/s
