A vessel at rest exlodes breaking it into three piecess. Two pieces having equal mass fly off prependicular to one anther with the same speed of `30m//s` . The third pieces has three times the mass of each other piece. What is the direction (w.r.t. the piece having equal masses) and magnitude of its velocity immediately after the explosion?

Options

A. `10sqrt(2)m//`seconds and `135^(@)` from either
B. `10sqrt(2)m//` second and `45^(@)` from either
C. `(10)/(sqrt(2))m//` second and `135^(@)` from either
D. `(10)/(sqrt(2))m//` second and `45^(@)` from either

Answer

A
