A uniform marble rolls down a symmetric bowl, starting from rest atthe top of the left side. The top of each side is a distanceh
above the bottom of the bowl. The left half of the bowlis rough enough to cause the marble to roll without slipping, butthe right half has no friction because it is coated with oil.
(a) How far up the smooth side will the marblego, measured vertically from the bottom? (Use the followingvariable as necessary: h.)

(b) How high would the marble go if both sides were as rough as theleft side? (Use the following variable as necessary: h.)

(c) How do you account for the fact that the marble goeshigher with friction on the right side than withoutfriction?

Answer:
upward force acting = 261.6 N
Explanation:
given,
mass of gibbon = 9.4 kg
arm length = 0.6 m
speed of the swing
net force must provide
force of gravity = - mg
=
=
=9 x 29.067
= 261.6 N
upward force acting = 261.6 N
