A 5 kg stationary bomb explodes into three parts having masses in the ratio 1:1:3 respectively. The two equal parts move off at right angles to each other, each with a velocity of 39 ms⁻¹. The velocity of the bigger part will be

Answer: (C)

Solution

With masses in ratio 1:1:3 (total 5, so masses 1, 1, 3), the two 1 kg parts have momenta 39 and
