Statement-I : A projectile is thrown with an initial velocity of (ahat(i)+bhat(j)) m//s . If range of projectile is maximum then a=b . Statement-II : In projectile motion, angle of projection is equal to 45^(@) for maximum range condition.

Statement-I : A particle moves in a straight line with constant acceleration. The average velocity of this particle cannot be zero in any time interval. Statement-II : For a particle moving in straight line with constant acceleration, the average velocity in a time interval is (u+v)/(2) , where u and v are initial and final velocity of the particle of the given time interval.
