Current Question (ID: 19090)

Question:
$\text{A person can throw a ball up to a maximum range of } 100 \text{ m.}$ $\text{How high above the ground can he throw the same ball?}$
Options:
  • 1. $25 \text{ m}$
  • 2. $50 \text{ m}$
  • 3. $100 \text{ m}$
  • 4. $200 \text{ m}$
Solution:
$\text{Hint: } H_{\text{max}} = \frac{u^2}{2g}$ $\text{Step 1: Find the value of } \frac{u^2}{g}.$ $\text{The maximum range is given by:}$ $R_{\text{max}} = \frac{u^2}{g}$ $\Rightarrow \frac{u^2}{g} = 100$ $\text{Step 2: Find the maximum height reached by the ball.}$ $H_{\text{max}} = \frac{u^2}{2g}$ $\Rightarrow H_{\text{max}} = \frac{100}{2}$ $\Rightarrow H_{\text{max}} = 50 \text{ m}$ $\text{Hence, option (2) is the correct answer.}$
