An object has a kinetic energy of 14 j and a mass of 17 kg how fast is the object moving
Brilliant_brown [7]
  • KE=14J
  • Mass=m=17kg
  • Velocity=v=?

\\ \sf\Rrightarrow kE=\dfrac{1}{2}mv^2

\\ \sf\Rrightarrow 14=\dfrac{1}{2}17v^2

\\ \sf\Rrightarrow 17v^2=28

\\ \sf\Rrightarrow v^2=28/17

\\ \sf\Rrightarrow v^2=1.64

\\ \sf\Rrightarrow v\approx 0.13m/s

What is the square root of 25x10^12
kirill115 [55]

\sqrt{25 \times 10^{12} }

In order to find it's square root, we could make it into two square roots.

\sqrt{25 \times 10^{12} } = \sqrt{25} \times \sqrt{10^{12}}

Let us find the square roots of both radicals seprately.

\sqrt{25} =\sqrt{5*5}=5

Each  pair  of a number inside square root gives a number out .

\sqrt{10^{12}} = \sqrt{10*10*10*10*10*10*10*10*10*10*10*10}   \ \ ( \ makes \ 6 \ pairs \ of \ 10 )

\sqrt{10*10*10*10*10*10*10*10*10*10*10*10} = 10*10*10*10*10*10

= 10^6.

Therefore,

\sqrt{25 \times 10^{12} }=\sqrt{25} \times \sqrt{10^{12}}={5 \times 10^6}

\sqrt{25 \times 10^{12} } = {5 \times 10^6}
