Practice question
Question
A cyclist moves with a constant speed of 5m/s for 20s. 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 100 m as the result, so option B is correct.
