Respuesta :

The kinetic energy of the cart is 16 J

Explanation:

The kinetic energy of an object is the energy possessed by the object due to its motion. Mathematically, it is calculated as:

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

where

m is the mass of the object

v is its speed

For the cart in this problem,

m = 8 kg is its mass

v = 2 m/s is its speed

Substituting, we find its kinetic energy:

[tex]K=\frac{1}{2}(8)(2)^2=16 J[/tex]
