Question

a shell of mass 100g moving with the speed of 50m/s along a straight line at an angle tan(4/3) to the horizontal bursts into two pieces.the piece of mass 60g starts moving horizontally with a speed of 50 m/s.The other piece moves with a speed of​

Answer 1

Answer:

100m/s in upwards direction

Explanation:

Conservation of momentum along x and y axis

Initial velocity of partical along x and y is given by the diagram

Therefore after the seperation the velocity of 60 g body is given as 50 m/s

Since momentum(p) is conserved ,change in momentum along x and y is equal to 0

Along x( initial - final )momentum

100(30)-60(50)-40(Vx)=0

Vx=(300-300)/4 =0

Vx=0m/s

Along y( initial - final )momentum

100(40)-60(0)-40(Vy)=0

Vy=100m/s
