Physics

A small block with mass 0.0400 kg is moving in the xy-plane. Thenet force on the block is described by the potential- energyfunction U(x,y)= (5.90 J/m2 )x2-(3.90 J/m3 )y3.

a- What is the magnitude of the acceleration of the block whenit is at the point x= 0.29 m , y= 0.66 m ?

b- What is the direction of the acceleration of the block whenit is at the point x= 0.29 m , y= 0.66 m ?
