The kinetic energy of a body of mass 2 kg is 25 J. Its speed is??

The speed of the body is 5 m/s

Applying the formular of kinetic energy

Kinetic energy: This can be defined as the energy posses by a moving body or that depends on the speed of a body.

The formular for kinetic energy is

E = mv²/2.................... Equation 1

Where E = Kinetic energy of the body, m = mass of the body, v = veocity/ speed of the body.

make v the subject of equation 1 above

v = ................ Equation 2

From the question,

Given: E = 25 J, m = 2 kg

Substitute these values into equation 2

v =

v =

v =

v = 5 m/s.

Thus, the speed of the body is 5 m/s

Step-by-step explanation:

Kinetic Energy (K. E) = 25 J

Mass ( m) = 2 kg

Velocity or speed (v) = ?

We have the formula that

it's speed is 5 m/s .

Hope it helps. :)

yes yes yes yes yes yes yes yes yes

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
