Rank each pendulum on the basis of the maximum kinetic energy it attains after release. Rank from largest to smallest. To rank items as equivalent, overlap them.
h = 60 cm, m = 2 kg
h = 30 cm, m = 4 kg
h = 30 cm, m = 2 kg
h = 15 cm, m = 8 kg
h = 60 cm, m = 1 kg
h = 45 cm, m = 3 kg
largest
smallest
The correct ranking cannot be determined.
