A rock is thrown straight up with an initial velocity of 24.5 m/s.What maximum height will the rock reach before starting to fall downward? (Take acceleration due to gravity as 9.80 m/s². ) A)9.80 m B)19.6 m C)24.5 m D)30.6 m

Question

Quizplus · Accepted Answer

The maximum height can be calculated using the formula: $ h = \frac{v^2}{2g} $, where $ v $ is the initial velocity and $ g $ is the acceleration due to gravity. Substituting the given values: $ h = \frac{(24.5)^2}{2 \times 9.8} = 30.6 $ m.
