A bomb travelling in a parabolic path under the effect of gravity, explodes in mid air. The centre of mass of fragments will :

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 bomb explodes in mid air into two equal fragments . What is the angle between their directions of motion ?

Two particles A and B of masses 1kg and 2kg respectively are projected in the directions shown in figure with speeds u_A=200m//s and u_B=50m//s . Initially they were 90m apart. They collide in mid air and stick with each other. Find the maximum height attained by the centre of mass of the particles. Assume acceleration due to gravity to be constant. (g=10m//s^2)

Statement I: If a ball projected up obliquely from the ground breaks up into several fragments in its path, the centre of the system of all fragments moves in the same parabolic path compared to initial one till all fragments are in air. Statement II: In the situation of Statement 1, at the instant of breaking, the fragments may be thrown in different directions with different speeds.

A uniform disc of mass m and radius R is projected horizontally with velocity v_(0) on a rough horizontal floor so that it starts with a purely sliding motion at t= 0. After t_(0) seconds it acquires a purely rolling motion. (a) Calculate the velocity of the centre of mass of the disc at t_(0) (b) Assuming the coefficient of friction to be mu , calculate to. Also calculate the work done by the frictional force as a function of time and the total work done by it over a time t muchlonger than t_(0) .
