Katarina [22]

Answer: minimum speed of launch must be 7.45m/s

Explanation:

Given the following:

Height or distance (s) = 2.83m

The final velocity(Vf) at maximum height = 0

Upward motion, acceleration due to gravity(g) us negative = -9.8m/s^2

From the 3rd equation of motion:

V^2 = u^2 - 2gs

Where V = final velocity

u = initial velocity

Therefore, u = Vi

u = √Vf^2 - 2gs

u = √0^2 - 2(-9.8)(2.83)

u = √0 + 55.468

u = √55.468

u = 7.4476 m/s

u = 7.45m/s

Which of the following is not a nutrient? Minerals, probiotics, lipids or proteins. Why?
Tju [1.3M]

All vitamins are identified as key nutrients: the body cannot produce them and so they must be obtained through diet; minerals are similarly identified as key nutrients. Vitamins and minerals are equally essential for the healthy functioning of the body.
But then there’s lipids
Lipids; Lipids are a group of structurally and functionally diverse organic compounds that are insoluble in water. Certain classes of lipids, such as fats, phospholipids
