After the explosion the other fragment has velocity v along +ve x-axis.

B

After the explosion the other fragment has velocity 3v along +ve x-axis.

C

After the explosion the fragments reach the separation 2R between them where R is the range of the projectile.

D

After explosion both the fragments hit the ground simultaneously at t = R/2v.

A fire cracker following a parabolic path explodes in mid air. The centre of mass of all the fragments will follow a path

A shell is fired from a gun and it explodes in two pieces at the highest point of trajectory . One piece retraces its apth to gun . What will be the velocity of other part just after explosion if shell is fired with a speed u at an angle theta with the horizontal ?

If theta is the angle between the velocity and acceleration of a projectile at a point of its path, its value when the projectile is at the highest point is :

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 fired from the ground follows a parabolic path. The speed of the projectile is minimum at the top of its path.

When an expolsive shell travelling in a parabolic path under the effect of gravity explodes in the mid air, the centre of mass of the fragments will move.

A projectile fired from the ground follows a parabolic path. The speed of the projectile is minimum at the top of its path. State whether this statement is true or false

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 mass3in,initially at rest at the origin, explodes into three fragments of equal mass. Two of the fragments have speed v each and move perpendicular to each other. The third fragment will, move with a speed.
