Question

A ball is thrown horizontally at 8m/s from a height of 12.5m. What is its speed on hitting the ground? (Take g\=10m/s2)

Options

Choose one · Correct answer highlighted

Explanation

Vertical velocity: vy=2gh=2×10×12.5=250≈15.81m/s. 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 15 m/s as the result, so option A is correct.
