Two blocks of mass m1=1.8kg and m2=1.2kg are connected via a pulley as shown. Assuming the blocks are at rest at t=0, what is the velocity of block 1 at t=1.0 second, and is it moving up or down?

Answer:
2m/s
Explanation:
18-T=1.8a
T-12=1.2a
solving simultaneously
acceleration a=3m/s^2
velocity= a×t=2×1=2m/s
