A shell of mass m is at rest initially. It explodes into three fragments having masses in the ratio `2:2:1`. The fragments having equal masses fly off along mutually perpendicular direction with speed v. What will be the speed of the third (lighter) fragment?

A body of mass 1 kg initially at rest explodes and breaks into three fragments of masses in the ration 1 : 1 : 3. The two pieces of equal mass fly off perpendicular to each other with a speed of 30 m/s each. What is the velocity of the heavier fragment?

A shell of mass 5M, acted upon by no external force and initially at rest, bursts into three fragments of mass M, 2M and 2M respectively. The first two fragments move in opposite directions with velocity of magnitudes 2V and V respectively. The third fragment will

A bomb at rest explodes into three fragments of equal masses. Two fragments fly off at right angles to each other with velocities 9 m cdot s^(-1) and 12 m cdot s^(-1) respectively. Calculate the speed of the third.

Two particles have masses m & 4m and their kinetic energies are in the ratio 2: 1 . What is the ratio of their linear momenta?

A bomb of mass 8 Kg exlpodes on a smooth horizontal surface , into three fragments of masses 1 Kg , 3 Kg and 4Kg . 4Kg fragment moves with a speed 1 m/ s along eastward and 3 Kg fragement moves with a speed 1 m/s along northward . find the magnitude and direction of the velocity of 1Kg fragment .

A body of mass 4m is lying in xy-plane at rest. It suddenly explodes into three pieces. Two pieces, each of mass m move perpendicular to each other with equal speeds v. The total kinetic energy generated due to explosion is
