## Homework Statement

A gun fires a shell with the horizontal component of its velocity equal to 200m/s. At the highest point in its flight, the shell explodes into three fragments. Two of these fragments, which have equal mass, fly off with speeds of 300m/s relative to the ground, one along the flight direction of the shell at the instant of fragmentation and the other perpendicular to it in a horizontal plane. Find the magnitude and direction of the velocity of the third fragment immediatley after the explosion, assuming its mass is three times that of each of the other two fragments. Neglect air resistance.

## Homework Equations

ρ = mv

## The Attempt at a Solution

I'm afraid I don't know where to start with this question. I was hoping somebody could at least set me off in the right direction. Any help would be appreciated. Thanks
