## Homework Statement

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

*m*2 = 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 (

*m*1=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.
