A bomb initially at rest at a height of 40 m above the ground suddenly explodes into two identical fragments . One of them starts moving vertically downwards with an initial speed of 10 m /s .If acceleration due to gravity is `10m//s^(2)` , What is the separation between the fragments 2s after the explosion?

A bomb initially at rest at a height of 40 m above the ground suddenly explodes into two identical fragments. One of them starts moving vertically downwards with an initial speed of 10 m/s. If acceleration due to gravity is 10 m//s^2 , the separation between the fragments, 2 seconds after the explosion is

A particle is projected vertically upwards from ground with an initial speed of 57m/s .If acceleration due to gravity is taken to be equal to 10m/ s^(2) ,then the displacement of the particle in the sixth second of its motion will be?

A body moving on the ground with a velocity of 15m//s comes to rest after covering a distance of 25m If acceleration due to gravity is 10m//s^(2) Calculate the coefficient of friction between the ground and the body .

A shell is fired from a cannon with a speed of 100 m//s at an angle 30^(@) with the vertical ( y -direction). At the highest point of its trajectory, the shell explodes into two fragments of masses in the ratio 1:2 . The lighter fragment moves vertically upwards with an initial speed of 200 m//s . What is the speed of the heavier fragment at the time of explosion?
