Question

An object, of mass 3 kg, moving with a velocity of 5m/s along the positive X- direction, breaks up, by itself, into three equal mass fragments. Two of these move along directions that are exactly opposite to each other with speeds of 2m/s each. Find the speed of the third fragment.​

Answer 1

Explanation:

Using conservation of momentum

m1u1=m2v2+m2v3-m2v4

3×5=1×2-1×2+1×v4

15=1v4

v4=15m/s
