physics

a 5 KG object at rest explodes into four (4) fragments. Object 1 flies off at 45 degrees from the positive x axis. Object 2 flies off along the X axis, and Object 3 flies off along the x axis. if they have the velocities and masses listed in the table below, what is the mass, velocity, and direction angle of the fourth object? put the mass and the magnitude of the velocity in the table below. after you find the velocity and direction, mark on the diagram its approximate locatin
