is u²/4g is one of the formula to find max height of the projectile??
Asked by khazinawaz89 | 20 Oct, 2021, 20:05: PM
Maximum height hmax of the projectile is determined from the following equation
![begin mathsize 14px style h subscript m a x end subscript space equals space fraction numerator u squared sin squared theta over denominator 2 g end fraction end style](https://images.topperlearning.com/topper/tinymce/cache/6906eff974d0d564d78b670d10e0eeec.png)
where u is initial projection velocity at angle θ from horizontal and g is acceleration due to gravity.
We get maximum range , i.e., maximum distance travelled horizontally when angle of projection θ is 45o
If we substitute θ = 45o , then we get from eqn.(1)
![begin mathsize 14px style h subscript m a x end subscript space equals space fraction numerator u squared over denominator 4 g end fraction end style](https://images.topperlearning.com/topper/tinymce/cache/bfed660d7bd4e266be769f95eb247400.png)
Hence we can consider eqn.(2) as maximum height when projectile is projected for maximum range ,
i.e.when angle of projection is 45o , we get maximum height from eqn.(2)
