Question

A train starts from rest and accelerates uniformly at 0.5m/s2 for 20s. What is the final velocity?

Options

Choose one · Correct answer highlighted

10 m/s Correct 15 m/s 5 m/s 20 m/s

Explanation

Use the equation v=v0+at. 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 10 m/s as the result, so option A is correct.
