### Movement Simulation Problem

**Sun Jan 10, 2016 4:58 pm**Hi. I am a physics teacher and i am new in Algodoo. So, could you help me to simule below question, please. Thanks a lot.

Suppose I have two identical masses, m1 and m2, that are both sliding along a frictionless horizontal surface with the same speed and direction. When they reach point A, m1 continues as before, but m2 drops into a depression in the surface. I'm not specifying anything about the shape of this depression except that it is smooth and continuous, and it does not drop so suddenly that m2 loses contact with it - in other words, gravity is sufficient to keep m2 on the surface (no cliffs or walls). Which mass will arrive at point B first?
