Air is blowing and is providing a constant horizontal acceleration ax = g to the particle as shown in the figure. Particle is projected from point P with a velocity u in upward direction. Let Q be the highest point of the particle. Speed of the particle at highest point Q 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:
