Physics

A plate falls vertically to the floor and breaks up into three pieces, which slide along the floor. Immediately after the impact, a 200g piece moves along the x-axis with a speed of 2.00m/s and a 235g piece moves along the the y axis with a speed of 1.50m/s. The third piece has a mass of 100g. In what direction does the third piece move?

I have done this:

tan^-1 = 235(1.50)/200(2) = 41.4

i don't think this is right please help.

  1. Tan^-1(Fy/Fx)

    Fx = 200*2
    Fy = 235*1.5

    I think you are right.

  2. tan^-1 = 235(1.50)/200(2) = 41.4
    Angle from x axis= 180 + 41.4
