Its time of flight on the horizontal ground is 4 second. The projectile is moving at angle of 45^∘ with the horizontal just one second after the projection. Hence the angle θ is (take g=10m/s^2)

A projectile is thrown with velocity u making an angle θ with the horizontal. Its time of flight on the horizontal ground is 4 second. The projectile is moving at angle of 45^∘ with the horizontal just one second after the projection. Hence the angle θ is (take g=10m/s^2)

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:
