ssm By accident, a large plate is dropped and breaks into three pieces. The pieces fly apart parallel to the floor, with v1 = 2.95 m/s and v2 = 1.70 m/s. As the plate falls, its momentum has only a vertical component, and no component parallel to the floor. After the collision, the component of the total momentum parallel to the floor must remain zero, since the net external force acting on the plate has no component parallel to the floor. Using the data shown in the drawing, find the masses of pieces 1 and 2.
What happened to the third piece?
If there were in fact only two pieces and v1 and v2 are opposite directions, as they must be if there are only two pieces, then all you can say is that
M1 v1 = M2 v2
The third piece is said to be 1.30 kg at 3.07 m/s. M1 has an angle of 25 and m2 had an angle of 45 and the question ias aking what are the masses for m1 and m2
