A bomb of mass m is projected from the ground with speed v at angle `theta` with the horizontal. At the maximum height from the ground it explodes into two fragments of equal mass. If one fragment comes to rest immediately after explosion, then the horizontal range of centre of mass is

A body of mass m is projected from ground with speed u at an angle theta with horizontal. The power delivered by gravity to it at half of maximum height from ground is

A projectile is fired with velocity. v_0 at an angle 60^@ with horizontal . At top of its trajectory it explodes into two fragments of equal mass. If one fragment retraces the path then the speed of the other fragment is

A projectile is fired with velocity. v_0 at an angle 60^@ with horizontal . At top of its trajectory it explodes into two fragments of equal mass. If one fragment retraces the path then the speed of the other fragment is

A projectile of mass "m" is projected from ground1 with a speed of 50 m/s at an angle of 53^(@) with the horizontal. It breaks up into two equal parts at the highest point of the trajectory. One particle coming to rest immediately after the explosion. The distance between the pieces of the projectile when they reach the ground are :

A body is projected with a speed 160 m/s at an angle 53^(@) with the horizontal, At the highest point, body explodes into two pieces with mass ratio 1:3. Smaller piece comes to rest immediately after explosion. Find the distance of point from point of projection where heavier piece strikes the horizontal surface.
