A 6.8kg block on a 30∘ incline (μk\=0.15) is pulled upward by a 8.8kg mass over a pulley. What is the acceleration? (Tak
For 8.8kg: 8.8g−T=8.8a⇒88−T=8.8a. As per NCERT Chapter 3, equations v=u+at, s=ut+½at², v²=u²+2as describe uniformly accelerated motion. Applying correct signs and units gives 8.8 a as the result, so option A is correct.
