The steelhead lands on the top of waterfall when it is descending so the time taken is 1.36 seconds.
A waterfall is a factor in a river or movement in which water flows over a vertical drop or collection of steep drops.
Waterfalls are formed in a variety of ways, but the most common is for a river to flow over a top layer of elastic rock before dropping into soft rock. This rock will erode faster, resulting in a higher drop. Waterfalls have been studied for their impact on the species that live in and around them. Over the years, people have developed a unique relationship with waterfalls by seeing them, exploring them, and naming them. They can pose a formidable obstacle to navigation along the river.
Using ,S= u*t + (1/2)at2
1.8 = 8t - [(1/2)*9.8*t2]
By ,solving this quadratic equation we get, t= 0.27 s or t= 1.36 s
