The figure shows two 1.0kg blocks connected by a rope. A second rope hangs beneath the lower block. Both ropes have a mass of 250g . The entire assembly is accelerated upward at 3.0m/s2 by force F.

What is F?

What is the tension at the top end of rope 1?

What is the tension at the bottom end of rope 1?

What is the tension at the top end of rope 2?

The figure shows two 1.0 blocks connected by a rope. A second rope hangs beneath the lower block. Both ropes have a mass of 250 The entire assembly is accelerated upward at 3.0m/s2 by force F. What is F? What is the tension at the top end of rope 1? What is the tension at the bottom end of rope 1? What is the tension at the top end of rope 2?

Explanation / Answer

F = mg+ma = 2.5*9.8+2.5*3 = 32 N

T at topend of rope 1 = 1.5*9.8+1.5*3 = 19.2 N

T at bottom end of rope 1 = 1.25*9.8+1.25*3 = 16 N

Tension at top end of rope 2 = 0.25*9.8+0.25*3 = 3.2 N
