Homework Answers
The initial and final velocities of falling body can be calculated from experiment only. As mentioned in EXP-II question-1 you have to measure it in the last trial.
Rotating bodies kinetic energy, you have already calculated as 22.03.
V0 and Vf values can't be calculated from given table. You have to measure it separately. From those values you can calculate falling body KE as ½mv2 - ½mv2. Hope you understand.

We know the heart shaped object has a moment of inertia of I =
0.5kgm^2. Calculate the change in angular momentum (L) of the
object in 5s (~L=~τ∆t). This question deals with angular momentum
conservation. Two girls of mass 100 kg each stand at the center of
a rotating merry-go-round (MGR) in the shape of a disk of radius 1
m and mass 10 kg. The platform rotates atω= 0.40 rad/s. Let’s call
this configuration instant A.

A student sits on a freely rotating stool holding two dumbbells, each of mass 3.05 kg (see figure below). When his arms are extended horizontally (Figure a), the dumbbells are 1.07 m from the axis of rotation and the student rotates with an angular speed of 0.740 rad's. The moment of inertia of the student plus stool is 2.57 kg: m2 and is assumed to be constant. The student pulls the...
