The direction of projection of particle is shown in the figure for an observer on trolley. An observer on the ground sees the ball rising vertically. The maximum height reached by the ball as seen from the trolley is

A particle A is projected vertically upwards. Another particle B is projected at an angle of 45^∘. Both reach the same height. The ratio of the initial kinetic energy of A to that of B is:
