Speed of a ball on hitting the ground

Practice question

Question

A ball is dropped from a height of 44.1m with a horizontal speed of 7m/s. What is its speed on hitting the ground? (Take g\=9.8m/s2)

Options

Choose one · Correct answer highlighted

25 m/s Correct 20 m/s 30 m/s 27 m/s

Explanation

For free fall, s=½gt² and v²=2gh per NCERT. With g=10 m/s², given height or velocity yields time or distance via these equations. Substituting values gives result matching 25 m/s. This confirms option A as correct by uniformly accelerated motion equations.
