Two projectiles A and B thrown with speeds in the ratio 1 : `sqrt(2)` acquired the same heights. If A is thrown at an angle of `45^(@)` with the horizontal, the angle of projection of B will be

Two projectiles A and B are thrown with velocities v and v/2 respectively. They have the same range. If B is thrown at an angle of 15^@ to the horizontal, A must have been thrown at an angle

Two projectiles A and B are thrown from the same point with velocities v and v/2 respectively. If B is thrown at an angle 45^(@) with horizontal.What is the inclination of A .when their ranges are the same?

A projectile thrown with an initial speed u and the angle of projection 15^@ to the horizontal has a range R . If the same projectile is thrown at an angle of 45^@ to the horizontal with speed 2 u , what will be its range ?

Two projectiles A and B are thrown with the same speed such that A makes angle theta with the horizontal and B makes angle theta with the vertical, then -

Two projectiles of same mass and with same velocity are thrown at an angle 60^(@) and 30^(@) with the horizontal, then which quantity will remain same:-

Two balls A and B are thrown with speeds u and u//2 , respectively. Both the balls cover the same horizontal distance before returning to the plane of projection. If the angle of projection of ball B is 15^@ with the horizontal, then the angle of projection of A is.

A projectile is thrown at an angle of theta=45^(@) to the horizontal, reaches maximum reaches a maxium height of 16m , then

Two projectile are projected with the same velocity. If one is projected at an angle of 30^(@) to the horizontal. The ratio if maximum heights reached, is:

Two projectiles are projected with the same velocity. If one is projected at an angle of 30^@ and the other at 60^0 to the horizontal, then the ratio of maximum height reached, is

A projectile is thrown with speed 40 ms^(-1) at angle theta from horizontal . It is found that projectile is at same height at 1s and 3s. What is the angle of projection ?
