Given: mechanism consists of 2 members: (1) block 1 of mass m1=9kg; (2) homogeneous disk 2 of mass m2=15kg and radius R2=57cm.
Mechanism starts moving in vertical plane under the action of gravity forces from the state of rest with block 1 at height h=7m above the ground.
Find: absolute value of the velocity of block 1 (in m/s) when it hits the ground. V1=?
