Question

A body accelerates uniformly from rest to a velocity of 20m/s over a distance of 50m. What is the acceleration?

Options

Choose one · Correct answer highlighted

Explanation

Use v2=v02+2ax. Here, v0=0, v=20m/s, x=50m. 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 4 m/s² as the result, so option C is correct.
