Question

A ball is thrown vertically upwards with an initial velocity of 10m/s. What is the total time of flight? (Take g\=10m/s2)

Options

Choose one · Correct answer highlighted

Explanation

Time to reach max height: v=v0+at, 0=10−10t⇒t=1s. 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 2 s as the result, so option A is correct.
