please put in order

Six pendulums of various masses m are released from various heights h above a tabletop, as shown in the figures below. All the pendulums have the same length and are mounted such that at the vertical position their lowest points are the height of the tabletop and just do not strike the tabletop when released. Assume that the size of each bob is negligible. Rank each pendulum on the basis of its initial gravitational potential energy (before being released). (hint: Gravitational potential energy does not depend only on the mass of the object.) please put in order

Explanation / Answer

Calculation:-
a)m=2kg,h=60cm      u=(2)(9.8)(0.6)=11.76J
b)m=1kg,h=60cm      u=(1)(9.8)(0.6)=5.88J
c)m=4kg,h=30cm      u=(4)(9.8)(0.3)=11.76J
d)m=8kg,h=15cm      u=(8)(9.8)(0.15)=11.76J
e)m=3kg,h=45cm      u=(3)(9.8)(0.45)=13.23J
f)m=2kg,h=30cm       u=(2)(9.8)(0.3)=5.88J
Rank of each pendulum on the basis of its intial gravitational potential energy are:-

     answer:-e,(a,c,d),(b,f)

Rank each pendulum on the basis of the maximum kinetic energy it attains after release

h=!45,m=3! > !m=2,h=60! , !m=4,h=30! , !m=8,h=15cm! > !m=2,h=30! , !m=1,h=60!
