A long block of ice is resting on a table. A long trough with parabolic cross-section is cut out of the ice with length between the focus and the vertex of a=7.76 cm. A small puck with mass m2 = 0.751 kg is placed a distance h=16.8 cm above the bottom of the trough. What is the horizontal acceleration of the ice block (m1=2.084 kg) after the puck is released? All surfaces are frictionless. Express your answer in m/s2 with the +x direction being defined toward the right.
I currently have a free body diagram, but I am unsure where the vertex or height come intro play, because the shape is parabolic.
The Attempt at a Solution
M1: force floor, force normal of 2 on 1, force due to gravity
M2: force normal of 1 on 2, force due to gravity
