Practice question
Question
A cyclist moves at a constant speed of 12m/s for 30s. What is the distance covered?
Explanation
For constant speed, distance x=vt. 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 360 m as the result, so option D is correct.
