In a truck-loading station at a post office, a small 0.200-kg package is released from rest a point A on a track that is one quarter of a circle with radius 1.60 m.The size of the packageis much less than 1.60m, so the package can be treated at aparticle. It slides down the track and reaches point B with a speed of 4.80 m/s. From point B, it slides on a level surface a distanceof 3.00 m to point C, where is comes to rest. 
(a) What is the coefficient of kinetic friction on the horizontal surface? 
(b) How much work is done on the package by friction as it slides down the circular arc from A to B?

Starting with an initial speed of 5.00 m/s at a height of 0.300 m, a 1.50 kg ball swings downward and strikes a 4.60kg ballthat is at rest, as the drawing shows. a. using the principle of conservation of mechanicalenergy,find the speed of the 1.50 kg ball just before impact b. assuming that the collision is elastic, find the velocities( magnitude and direction ) of both balls just after thecollision c. how high does each abll swing after the collision, ignoringair resistance?

Poincare Map for Polar ODE
I am currently trying to obtain a Poincare Map for the ODE system originally given by
{x˙=(1x2y2)xyy˙=x+(1x2y2)y
on the region x(12,32) and y=0. Since x2+y2=r2 and tan(θ)=yx, we obtain that
{r˙=xx˙+yy˙rsec2(θ)θ˙=xy˙yx˙x2  {r˙=rr3θ˙=1
However, I am stuck here with trying to identify the Poincare Map for the given system. Are there any recommendations for how to proceed? Moreover, how can I linearize this system at the point (x,y)=(1,0) (or in polar coordinates (r,θ)=(1,0)?
