A cannon fires two shells successively with velocity `250 m s^(-1)` at angles `60^@` and `45^@` with the horizontal in the same vertical plane one after the other . What should be the interval between the firings so that they may hit the same target simultaneously ?

A cannon files successively two shells with velocity v_0=250m//s , the first at the angle theta_1=60^@ and the second at the angle theta_2=45^@ to the horizontal, the azimuth being the same. Neglecting the air drag, find the time interval between firings leading to the collision of the shells.

Two bodies are projected at angle of 45^@ and 60^@ with the horizontal with same velocity simultaneously. Ratio of their horizontal range is.

Two bodies are thrown up at angles of 45^@ and 60^@ respectively, with the horizontal. If both bodies attain same vertical height, then the ratio of velocities with which these are thrown is

Two projectiles are thrown from the same point simultaneously with same velocity 10 ms^(-1) . One goes straight vertically while other at 60^(@) with the vertical . What will be the distance of separation between the after 1 second of their throw?

A bulley with muzzle velocity 100 m s^-1 is to be shot at a target 30 m away in the same horizontal line. How high above the target must the rifle be aimed so that the bullet will hit the target ? .

Two bodies are thrown up at angles of 45^(@) and 60^(@) , respectively, with the horizontal. If both bodies attain same vertical height, then the ratio of velocities with which these are thrown is

A cannon fires successively two shells from the same point with velocity V_(0)=250m//s , the first at the angle theta_(1)=60^(@) and the second at the angle theta_(2)=45^(@) to the horizontal, the azimuth being the same. Neglecting the air drag, find the approximate time interval between firings leading to the collision of the shells (g=9.8m//s^(2))

A shell is fired from a cannon with a velocity 20 m//s at an angle 60^(@) with the horizontal. At the highest point it explodes into three pieces of equal masses . One of the pieces retraces its path to the cannon , the second piece moves vertically up with speed 40 m//s , the third piece will move with velocity (immediately after the explosion)
