A body of mass M at rest explodes into three pieces, in the ratio of masses 1:1:2. Two smaller pieces fly off perpendicular to each other with velocities of 30 ms -1 and 40 ms -1 respectively. The velocity of the third piece will be:
Text Solution
Verified by ExpertsThe correct answer is:
B
Mass of pieces by 
conserving momentum
As 
& 
are perpendicular
so 
& 
so v = 25
