Maximum height of ball thrown upwards at 12 m/s

Practice question

Question

A ball is thrown vertically upwards with a speed of 12m/s. What is the maximum height reached? (Take g\=10m/s2)

Options

Choose one · Correct answer highlighted

7.2 m Correct 5.8 m 8.6 m 9.2 m

Explanation

At max height v=0. Using v²=u²-2gh from NCERT kinematics, h=u²/2g. With u=12 m/s and g=10 m/s², h=7.2 m. This matches option A (7.2 m). Other options do not satisfy v²=u²+2as with correct signs.
