Conservation of Energy
A system of two paint buckets connected by a lightweight rope is released from rest with the 12.0 kg bucket 2.00 m above the floor. Using the principle of conservation of energy to find the the speed with which this bucket hits the floor. You can ignore friction and the mass of the pulley. The other bucket has the mass 4.0 kg.
NOTE: it is essentially a pulley with the 4.0kg bucket on the floor and the 12.0kg bucket 2m off the floor.
K1+U1=K2+U2
U1=0
K1= (1/2)(4)(v^2)
U2=(12)(9.8)(2)
K2=(1/2)(12)(v^2)
