A particle is thrown with velocity `u` at an angle `prop` from the horizontal. Another particle is thrown with the same velocity at an angle `prop` from the verticle. What will be the ratio of times of flight of two particles ?

A particle is thrown with a velocity u at an angle theta from the horizontal. Another particle is thrown with the same velocity at an angle theta from the vertical. The ratio of times of flight of the two particles will be

Two bodies are thrown with the same velocity at an angle 30^@ and 60^@ to the horizontal. What is the ratio of maximum heights reached?

A particle P is projected with velocity u_1 at an angle of 30^@ with the horizontal. Another particle Q is thrown vertically upwards with velocity u_2 from a point vertically below the highest point of path of P . Determine the necessary condition for the two particles to collide at the highest point. .
