A 52g firecracker is at rest at the origin when it explodes into three pieces. The first, with mass 15g , moves along the x axis at 42m/s in the positive direction. The second, with mass 15g , moves along the y axis at 34m/s in the positive direction.

Part A Find the x-component of the velocity of the third piece.

Part B Find the y-component of the velocity of the third piece.
