Question
For what condition, an object could be considered as a point object? Describe in brief.
✓

Answer

An object could be considered as a point object if it covers a distance much larger than its own size.
e.g. If a bus of 5m in size move 100km, then the bus can be considered as a point object.

A block of mass $m=1 kg$, moving on a horizontal surface with speed $V_l=2 m s ^{-1}$ enters a rough patch ranging from $x=0.10 m$ to $x=2.01 m$. The retarding force $F_r$ on the block in this range is inversely proportional to $x$ over this range,
$ F_r=\frac{-k}{x} \text { for } 0.1<x<2.01 m $ $=0$ for $x<0.1 m$ and $x>2.01 m$
where $k=0.5 J$. What is the final kinetic energy and speed $v_f$ of the block as it crosses this patch?
