Practice question
Question
A car starts from rest and accelerates uniformly at 2m/s2 for 10s. What is the distance covered by the car during this time?
Explanation
For uniformly accelerated motion, distance is given by 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 100 m as the result, so option A is correct.
