Part A
A small block with mass 0.0400 kg is moving in the
zy-plane. The net force on the block is described
by the potential-energy function
U(x, y) = (5.95 J/m²)x² - (3.70 J/m³)y³.
What is the magnitude of the acceleration of the block when it is at the point = 0.21 m, y = 0.50 m?
Express your answer with the appropriate units.
