A boat travels west at 6m/s while a current flows south at 8m/s. What is the magnitude of the boat’s velocity relative t
Velocity components: vx=−6m/s,vy=−8m/s. 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 10 m/s as the result, so option B is correct.
