A bomb explodes in air when it has a horizontal speed of 10 m//s . It breaks into two pieces A and B of mass ratio 1 : 2 . If A goes vertically up at a speed of 40 m//s , the speed of B is

Find average speed of 40m/s and 50m/s.

A ball is projected vertically up with speed 20 m/s. Take g=10m//s^(2)

A ball is projected vertically up with speed 20 m/s. Take g=10m//s^(2)

A body of mass 1kg initially at rest explodes and breaks into three parts of masses in the ration 1: 2: 3. If the two pieces of equal masses fly off perpendicular to each other with a speed of 30m//s The speed of third piece will be .

A bomb of mass 1 kg is thrown vertically upwards with a speed of 100 m//s .After 5 seconds it explodes into two fragments .One fragment of mass 400 g is found to go down with a speed of 25 m//s .the second fragment just after the explosion will go (g=10 m//s^2) .

A shell is fired from a cannon with a velocity 20 m//s at an angle 60^(@) with the horizontal. At the highest point it explodes into three pieces of equal masses . One of the pieces retraces its path to the cannon , the second piece moves vertically up with speed 40 m//s , the third piece will move with velocity (immediately after the explosion)

A body of mass 1 kg initially at rest explodes and breaks into three segments of masses in the ratio 1:1:3 . The two pieces of equal mass fly off perpendicular to each other, with a speed of 15 m/s each. The speed of the heavier fragment is

A bomb of mass 5 m initially at rest explodes and breaks into three pieces of masses in the ratio 1 : 1 : 3 . The two pieces of equal mass fly off perpendicular to each other with a speed of v_(0) . What is the velocity of the heavier piece? Also , calculate the energy released in explosion.
