No, it is not necessary for them to have the same acceleration.
For example, one may be speeding up while the other is slowing down. For an instant, their velocities may become the same but their accelerations are different.

Find the mass of the solid cylinder Dequals{(r,theta,z): 0less than or equalsrless than or equals2, 0less than or equalszless

anygoal [31]

The mass of the cylinder <em>D</em> is obtained by integrating the density function over <em>D</em>:

$\displaystyle\iiint_D\rho(r,\theta\,z)\,\mathrm dV$

With $\rho(r,\theta,z)=1+\frac z2$ , and

$D=\left\{(r,\theta,z)\mid 0\le r\le2,0\le z\le10\right\}$

the mass would be

$\displaystyle\int_0^{2\pi}\int_0^2\int_0^{10}1+\frac z2\,\mathrm dz\,\mathrm dr\,\mathrm d\theta=4\pi\int_0^{10}1+\frac z2\,\mathrm dz$

$4\pi\left(z+\dfrac{z^2}4\right)\bigg|_0^{10}$

$=4\pi\left(10+\dfrac{100}4\right)=\boxed{140\pi}$

In the photoelectric effect, it is found that incident photons with energy 5.00ev will produce electrons with a maximum kinetic

Yakvenalex [24]

From Literature:

The amount of energy in the photons is given by this equation:

E = hf

where E = energy
h = Planck's constant = 6.63 * 10^-34 Joule seconds
f = frequency of the light, Hz

Given:

E= 3.00 eV and Planck's constant

To solve for the frequency, E = 3.00 eV

1 electronvolt = 1.60218 x 10^-19 Joules

3 * 1.60218 x 10^-19 Joules = 6.63 * 10^-34 Joule seconds * f
f = 7.25 x 10^14 /second or hertz

Therefore, the threshold frequency of the material is 7.25 x 10^14 Hertz.
