An explosion blows a rock into three parts. Two parts go off at right angles to each other . These two are `1 kg` first part moving with a velocity of `12 ms^(-1) and 2 kg` second part moving with a velocity of `8 ms^(-1)`. If the third part flies off with a velocity of `4 ms^(-1)`. Its mass would be

An explosion blows a rock into three parts. Two pieces go off at right angles to each other, 1.0 kg piece with velocity of 12 m//s and other , 1.0 kg piece with a velocity of 12 m//s and other 2.0 kg piece with a velocity of 8 m//s . If the third piece flies off with a velocity of 40 m//s compute the mass of the third piece.

An explosion blows a rock into three parts. Two pieces go off at right angles to each other. 1.00 kg piece with a velocity 12m/sec and the other 2.00 kg piece with a velocity 8m/sec. If the third piece flies off with a velocity 40m/sec, then the mass of the third piece is -

An explosion breaks a rock into three parts in a horizontal plane. Two of them go off at right angles to each other. The first part of mass 1 kg moves with a speed of 12 ms^(-1) and the second part of mass 2 kg moves with 8 ms^(-1) speed. If the third part flies off with 4 ms^(-1) speed, then its mass i s .....
