A small block with mass 0.0400 kg is moving in the xy-plane. The net force on the block is described by the potential- energy function U(x,y)= (5.90 J/m2 )x2-(3.90 J/m3 )y3.
a- What is the magnitude of the acceleration of the block when it is at the point x= 0.29 m , y= 0.66 m ?
b- What is the direction of the acceleration of the block when it is at the point x= 0.29 m , y= 0.66 m ?

A small block with mass 0.0400 kg slides in a vertical circle of
radius 0.500 m on the inside of a circular track. During one of the
revolutions of the block, when the block is at the bottom of its
path, point A, the magnitude of the normal force exerted
on the block by the track has magnitude 4N . In this same
revolution, when the block reaches the top of its path, point
B, the magnitude of the normal...

A block of mass m = 3.5 kg is on an inclined plane with
a coefficient of friction μ1 = 0.23, at an
initial height h = 0.46 m above the ground. The plane is
inclined at an angle θ = 42°. The block is then compressed
against a spring a distance Δx = 0.11 m from its
equilibrium point (the spring has a spring constant of
k1 = 39 N/m) and released. At the bottom of the
inclined plane...
