Question

A particle moves with a constant acceleration of (5i^+2j^)m/s2 from rest. What is its speed after 3s?

Options

Choose one · Correct answer highlighted

Explanation

Velocity v=v0+at, with v0=0. 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 16.16 m/s as the result, so option A is correct.
