A trolley is moving horizontal `x - y` plane with a velocity of `36km//h` towards x-direction. When trolley is at `(100, 0, 0)` a bullet is fired with a muzzel velocity of `50sqrt(2)m//s` at angle of `45^(@)` with horizontal in  a plane making `53^(@)` with x-axis as shown. After `5 sec` bullet splits into two equal part. One of the part strikes trolley `5 sec` after splitting. If the distance of other part from origin is `Mxx100sqrt(2)` at this instant then. `M` is : (Assume mass of bullet is very small in comparison to trolley).
