A 24-kg projectile is fired at an angle of 53^(@) above the horizontal with an initial speed of 50m//s . At the highest point in its trajectory, the projectile explodes into two fragments of equal mass, the first of which falls vertically with zero initial speed. (a) How far from the point of firing does the second fragment strike the ground? (Assume the ground is level.) (b) How much energy was released during the explosion?

A projectile of mass mis fired with an initial velocity v_(0) at an angle 0 to the horizontal. At its highest point, it explodes into two fragments of equal mass. One of the fragments falls vertically with zero initial speed. Since the only external force acting on the system is gravitational, the motion of centre of mass of the_ system (the fragments) follows the same parabolic path as the projectile would have followed if there had been no explosion. Force of explosion is internal, it cannot change the trajectory of the system.

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

An object of mass 5 kg is projecte with a velocity of 20ms^(-1) at an angle of 60^(@) to the horizontal. At the highest point of its path , the projectile explodes and breaks up into two fragments of masses 1kg and 4 kg. The fragments separate horizontally after the explosion, which releases internal energy such that K.E. of the system at the highest point is doubled. Calculate the separation betweent the two fragments when they reach the ground.

A projectile is fired with velocity u at an angle theta with horizontal. At the highest point of its trajectory, it splits up into three segments of masses m, m and 2m. First part falls vertically downward with zero initial velocity and second part returns via same path to the point of projection. The velocity of third part of mass 2 m just after explosion will be

A shell is fired from a cannon with a speed of 100 m//s at an angle 30^(@) with the vertical ( y -direction). At the highest point of its trajectory, the shell explodes into two fragments of masses in the ratio 1:2 . The lighter fragment moves vertically upwards with an initial speed of 200 m//s . What is the speed of the heavier fragment at the time of explosion?

A projectile is fired from a gun at an angle of 45^(@) with the 'horizontal and with a muzzle speed of 1500 ft//s . At the highest point in its flight the projectile explodes into two fragments of equal mass. One fragment, whose initial speed is zero, falls vertically. How far from this gun does the other fragment land, assuming a level terrain ?
