Part 1
A boy throws a ball vertically upwards from moving open car on a horizontal straight road (i) The ball will fall behind the boy, if car is accelerating (ii) The ball will fall in front of the boy, if car is decelerating (iii) The ball will fall in the hands of boy if car is moving with uniform velocity (iv) The path of ball as seen by the boy will be vertical straight line if car is moving uniformly (v) The path of ball as seen by observer on ground will be parabola

The equation of trajectory of an oblique projectile y = √3x - gx^2/2. The angle of projection is ,
A ball is thrown from a point with a speed v0 at an angle of projection . From the same point and at this same instant, a person starts running with a constant speed v0/2 to catch the ball. Will the person be able to catch the ball? If yes, what should be the angle of projection?
