A ball is projected vertically up wards with a velocity of 100 m/s. Find the speed of the ball at half the maximum height. `(g=10 m//s^(2))`

Explanation

To find the speed of the ball at half the maximum height when it is projected vertically upwards with an initial velocity of 100 m/s, we can follow these steps:

### Step 1: Determine the maximum height (H)
The maximum height (H) can be calculated using the first equation of motion, where the final velocity (v) at the maximum height is 0 m/s. The equation is:

\[ v^2 = u^2 - 2gH \]

Here,
