The answer is c. It starts in the past by saying he "bought" then shifts to present by saying "goes" and "buys" but then shifts back to past by saying "last week"

Please someone derive 3rd equation of motion u- v= 2sa

zlopas [31]

We know

$\\ \sf\longmapsto a=\dfrac{dv}{dt}$

$\\ \sf\longmapsto a=\dfrac{dv}{dx}.\dfrac{dx}{dt}$

$\\ \sf\longmapsto a=v\dfrac{dv}{dx}$

$\\ \sf\longmapsto adx=vdv$

Integrate

$\\ \sf\longmapsto a{\displaystyle{\int}^x_{x_0}}dx=\displaystyle{\int}_u^v vdv$

$\\ \sf\longmapsto a(x-x_0)=\dfrac{v^2-u^2}{2}$

Here

x-x_0=s

$\\ \sf\longmapsto v^2-u^2=2as$

A 68.0-kg person jumps from rest off a 2.20-m-high tower straight down into the water. Neglect air resistance during the descent

Margarita [4]

Answer:

$F= 1333.767\,N$

Explanation:

The velocity of the swimmer just before touching the water is:

$v = -\sqrt{2\cdot (9.807\,\frac{m}{s^{2}} )\cdot (2.20\,m)}$

$v \approx 6.569\,\frac{m}{s}$

The average force exerted on the diver by the water is determined by the use of the Principle of Energy Conservation and the Work-Energy Theorem:

$(68\,kg)\cdot (9.807\,\frac{m}{s^{2}})\cdot (2.20\,m) +\frac{1}{2}\cdot (68\,kg)\cdot (6.569\,\frac{m}{s} )^{2}-F\cdot(2.20\,m) = 0\,J$

$F= 1333.767\,N$

Which of the following summarizes cellular respiration?

3241004551 [841]

The statement which summarizes cellular respiration is Oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

<h3>What is cellular respiration?</h3>

Cellular respiration is the process by which food, in the form of glucose is transformed into energy within cells.

The food is prepared by the plants by the process of photosynthesis in presence of sunlight. This food is in the form of glucose.

The respiration of plants is done by breaking of glucose by absorbing oxygen. This produces carbon- di- oxide and water along with the release of energy.

Thus, the cellular respiration is oxygen reacts with glucose to produce carbon dioxide and water, and release energy.
