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

A ball starts falling under the effect of gravitational force from a height of 45m. When it reaches a height of 25 m. When it reaches a height of 25 m it explodes into two pieces of mass ratio 1:2 . There is no change in the vertical motion of the piece after the explosion but they acquire horizontal velocity. If the heavier piece gains a horizontal velocity of 10ms^(-1) , then the distance between the two pieces when both of them strike the ground is

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

A particle of mass 1 kg is thrown vertically upward with speed 100 m/s. After 5 sec it explodes into two parts. One part of mass 400 g comes back with speed 25 m/s, what is-the speed of the other part just after explosion? (g= 10 m//s^(2) )

A particle of mass 1 kg is thrown vertically upwards with speed 100 m/s. After 5 s, it explodes into two parts. One part of mass 300 g comes back with speed 24 m/s, What is the speed of other part just after explosion? (a) 100 m/s upwards (b) 600 m/s upwards (c) 600 m/s upwards (d)81.7 m/s upwards

A bomb of mass 3.0 kg explodes in air into two pieces of masses 2.0 kg and 1.0 kg . The smaller mass goes at a speed of 80 m//s . The total energy imparted to the two fragments is :

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

A bomber plane moves horizontally with a speed of 500 m//s and a bomb released from it, strikes the ground in 10 s . The angle with horizontally at which it strikes the ground will be

A bomb of mass m is thrown with velocity v. It explodes and breaks into two fragments. One fragment of mass m', immediately after the explosion, comes to rest. The speed of the other fragment will be

1 kg body explodes into three fragements. The ratio of their masses is 1 : 1: 3 . The fragments of same mass move perpendicular to each other with speed 30 m/s. The speed of heavier part is

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