Practice question
Question
A body starts from rest and accelerates uniformly at 5m/s2 for 3s. What is the distance covered?
Explanation
Use x=v0t+12at2. 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 15 m as the result, so option A is correct.
