A 2000kg car on a banked road (θ\=25∘, μs\=0.4) turns at radius 80m while accelerating tangentially at 1.5m/s2. What is
The maximum speed depends on radial forces (centripetal), not tangential acceleration, which affects speed change over time. 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 28.8 m/s as the result, so option B is correct.
