By Accident A Large Plate Is Dropped And Breaks Into Three Pieces The Pieces Fly Apart Parallel To The Floor As The P 1 (27.72 KiB) Viewed 19 times

By accident, a large plate is dropped and breaks into three pieces. The pieces fly apart parallel to the floor. 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 (a) the mass of piece 1 and (b) the mass of piece 2. The figure shows three pieces of a plate with respect to horizontal and vertical axes. A segment of mass m subscript 1 is in the second quadrant and moves with a velocity of 3 meters per second making an angle of 25 degrees with the vertical. A segment of mass m subscript 2 is in the first quadrant and moves with a velocity of 1.79 meters per second making an angle of 45 degrees with the horizontal. A segment of mass m subscript 3 which equals 1.3 kilograms lies in the third and fourth quadrants and moves downwards with a velocity of 3.07 meters per second along the negative vertical axis.
