<u>The question does not provide enough information to complete the answer, so I'll assume the needed data to help you to solve your own problem</u>

Answer:

<em>The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile</em>

Explanation:

<u>Kinetic Energy </u>

Is the capacity of a body to do work due to its speed and is computed by

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

We are not given enough data to compare the kinetic energy of the fly with that of the automobile. We'll assume the following characteristics:  

m_a=500\ kg

v_a=10\ m/s

So its kinetic energy is

\displaystyle K_a=\frac{(500)10^2}{2}

\displaystyle K_a=25,000\ J

The mass of the fly is  

m_f=0.55\ gr=0.00055\ kg

To have the same kinetic as the automobile:

\displaystyle \frac{m_fv_f^2}{2}=25,000

Solving for v_f

\displaystyle v_f=\sqrt{\frac{2(25,000))}{m_f}}

\displaystyle v_f=\sqrt{\frac{50,000}{0.00055}}

v_f=9,534.6\ m/s

The fly should need to move at 9,534.6 m/s to have the same kinetic energy as the automobile

A body is at aheight of 81m and is ascending upwards with a velocity of 12m/s .a body of 2 kg weight is dropped from it.if g=10m
butalik [34]
First the velocity drops to zero in 1.2 secs. In those seconds it went upwards for 7.2 m, then it went from 87.2 to 0m. x-x0=v0*t+1/2*g*t^2 ergo t=sqrt(2x/g) that is 4.1761 s. Finally the total time required is 5.3761 s

In a electrically natural atom of any element there are equal numbers of
Usimov [2.4K]

Answer:  Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.

How to calculate the slope of position time graph?
Mashcka [7]

Answer:

The slope of a position-time graph can be calculated as:

m=\frac{\Delta y}{\Delta x}

where

\Delta y is the increment in the y-variable

\Delta x is the increment in the x-variable

We can verify that the slope of this graph is actually equal to the velocity. In fact:

\Delta y corresponds to the change in position, so it is the displacement, \Delta s

\Delta x corresponds to the change in time \Delta t, so the time interval

Therefore the slope of the graph is equal to

m=\frac{\Delta s}{\Delta t}

which corresponds to the definition of velocity.
