A 75.5 kg diver drops from a diving board 10.0 m above the waters surface. Find the divers speed just before he strikes the wate
jenyasd209 [6]

Answer:

<em>v=14 m/s</em>

Explanation:

<u>Mechanical Energy </u>

The kinetic energy of a body (K) is the capacity of doing work due to its speed. It can be expressed as

\displaystyle K=\frac{mv^2}{2}

The potential energy (U) is the capacity of doing work due to its height respect to a certain reference level.

U=mgh

The  mechanical energy is the sum of both

\displaystyle E_m=\frac{mv^2}{2}+mgh

The principle of conservation of mechanical energy states it must remain the same if no external force is acting on it. The diver drops from the diving board, which means its initial speed is zero (and so its initial kinetic energy). Thus, the mechanical energy at the jumping time is

\displaystyle E_m=mgh=(75)(10)(9.8)=7350\ J

When the diver is about to get into the water, his height reaches zero and the speed is at maximum. All the potential energy became kinetic energy, so

\displaystyle \frac{mv^2}{2}=7350\ J

Rearranging

\displaystyle v^2=\frac{2(7350)}{75}=196

v=\sqrt{196}=14\ m/s

The final speed of the diver is

\boxed{v=14\ m/s}

explain how a mutation in an individual's DNA occurs, and describe the effect it may have on the individual's traits.
zysi [14]
A mutation in the DNA ca happen during growth, when the DNA splits and becomes RNA. Mutations can also occur from other invasive cells, such as bacteria or viruses. A mutation in your DNA can also be there from when you were born. These mutations can cause variations in your appearance, such as eye color, ability to see, taste, smell and the complexion of your face. The mutations can also result in variations in your growth, causing immature or late growth. These mutations are dangerous, and can result in failure of the organisms cells , to complete and utter death of an organism.
