SUMMARY
The acceleration of block B, which has a mass of 35 kg and is subjected to a pulling force of 80 N on a frictionless surface, can be calculated using Newton's second law (ma = sigma(F)). The correct acceleration is determined by considering the frictional force acting on block A, which has a mass of 10 kg and a static friction coefficient of 0.4. The final calculated acceleration of block B is 1.2 m/s², but this value requires verification through detailed calculations to ensure accuracy.
