Question

33. 'A point particle of mass m, moves along
the uniformly rough track PQR as shown
in the figure. The coefficient of friction,
1. between the particle and the rough track
equalsu. The particle is released from
rest, from the point P and it comes to rest
at a point R. the energies, lost y the ball,
over the parts, PQ and QR, of the track,
are equal to each other and no energy is
lost when particle changes direction from
PO to OR
The values of the coefficient of friction u
and the distance x(= QR) are
respectively close to
P
a) 0.2 and 3.5m
b) 0.29 and 3.5m
c) 0.29 and 6.5 m
d) 0.2 and 6.5 m
