A particle is projected at time t=0 from a point O with a speed u at an angle theta to horizontal. Find the torque of a gravitational force on projectile about the origin at time t. (x,y plane is vertical plane)

A ball A is projected with speed 20 m//s at an angle of 30^(@) with the horizontal from the ground. Another ball B is released simultaneously from a point on the vertical line along the maximum height of the projectile. Both the balls collide at the maximum height of the first ball. The initial height of ball B is

A particle is projected from the top of a tower of height h with a speed u at an angle theta above the horizontal . T_(1) =Time taken by the projectile to reach the height of tower again . T_(2) =Time taken by the projectile to move at right angle to initial direction of motion . V_(1) =Speed of the projectile when it moves at an angle theta//2 with the horizontal . V_(2) =Speed with projectile strikes the ground . .

Two balls are projected from points A and B in vertical plane as shown in figure. AB is a straight vertical line. The balls can collide in mid air if v_1//v_2 is equal to
