A projectile of Mass 50kg is shot vertically upwards with an initial velocity of 100M/s .After 5s it explodes into two fragments, one of which having a Mass of 20kg is travelling vertically with a velocity of 180M/s .The velocity of the other fragment at that instant is nearly

A projectile of mass 50 kg is shot vertically upwards with an initial velocity of 100 m//s . After 5 s , it explodes into two fragments, one of which having a mass of 20 kg travels vertically up with a velocity of 150 m//s : a. What is the velocity of the other fragment that instant? b.Calculate the sum of rnornenta of fragment 3s after the explosion. What would have been the momentum of the projectile at this instant if there had been no explosion?

A ball of mass 0.20 kg is thrown vertically upwards with an initial velocity of 20 m s^(-1) .Calculate the maximum potential energy it gains as it goes up.

A mass of 1 kg is thrown up with a velocity of 100 m/s. After 5 seconds. It explodes into two parts. One parts of mass 400 g comes down with a velocity 25 m/s Calaculate the velocity of other parts:

A mass of 1 kg is thrown up with a velocity of 100 m/s. After 5 seconds. It explodes into two parts. One parts of mass 400 g comes down with a velocity 25 m/s Calaculate the velocity of other parts:

A pebble thrown vertically upwards with an initial velocity 50 m s^(-1) comes to a stop in 5 s. Find the retardation.

A projectile moving vertically upwards with a velocity of 200 m/s breaks into two equal parts at the height of 490 m.one part starts moving vertically upwards with a velocity of 400 m/s.How much time after the break up wil the other part hit the ground?

A shell of mass 20 kg at rest explodes into two fragments whose masses are in the ratio 2 : 3 . The smaller fragment moves with a velocity of 6 m//s . The kinetic energy of the larger fragment is

A shell of mass 20 kg at rest explodes into two fragments whose masses are in the ratio 2 : 3 . The smaller fragment moves with a velocity of 6 m//s . The kinetic energy of the larger fragment is

A particle of mass 2 kg is projected vertically upward with a velocity of 20 m/s. It attains maximum height of 17 m. The loss in mechanical energy due to air drag is ( g = 10 ms^-2)

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) )
