Question

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 1

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
