Statement 1 : A bullet is fired and it hits a target. An observer in the same plane heard two sounds: the crack of the rifle and the thud of the bullet striking the target at the same instant. Then the locus of the observer is a hyperbola where the velocity of sound is smaller than the velocity of the bullet. Statement 2 : If the difference of distances of a point P from two fixed points is constant and less than the distance between the fixed points, then the locus of P is a hyperbola.

Two thin wood screens A and B are separated by 200m. A bullet travelling horizontally at a speed of 600 ms^(-1) hits the screen A, penetrates through it and finally emerges out from B making holes in A and B. If the resistance of air and wood arc negligible, the difference of heights of the holes in A and B is

A bullet of mass m embeds itself in a block of mass M resting on a smooth horizontal surface, attached to a spring of force constant k. If the initial speed of the bullet is v_(0) along horizontal, find (a) the maximum compression of the spring and (b) the time for the bullet - block system to come to rest.

In the given figure points A and C are on the horizontal ground & A and B are in same vertical plane. Simultaneously bullets are fired from A, B and C and they collide at D. The bullet at B is fired horizontally with speed of 72/5 km//hr and the bullet at C is projected vertically upward at velocity of 54/5 km//hr . Find velocity of the bullet projected from A in m//s .
