Answer:

The kinetic energy is 3,802.5 J

Explanation:

Here, we are going to solve for the kinetic energy of an object with mass and velocity.

We know that there exist an energy for any moving object.

For the formula, we will use

[tex]KE = \frac{1}{2} mv^2[/tex]

where

[tex]KE[/tex]     is the kinetic energy, unit is in N.m or Joules (J)

[tex]m[/tex]        is the mass of the object, unit is in kg

[tex]v[/tex]         is the velocity of the object, unit is in m/s

For the given information

m = 45 kg

v = 13 m/s

KE = ?

Solving the problem

Let us use the formula for kinetic energy

[tex]KE = \frac{1}{2} mv^2[/tex]

Then substitute the given information, we have:

[tex]KE = \frac{1}{2} (45 kg)(13m/s)^2[/tex]

KE = 3,802.5 J

Therefore, the kinetic energy of the object is 3,802.5 J
