A500-kilogram horse runs at 5 meters/second. the horse’s kinetic energy is joules.

To solve this, we are going to use the formula for the kinetic energy of an object: 
where
is the kinetic energy of the object.
is the mass of the object.
is the speed of the object.

We know form our problem that the mass of the horse is 500 kilograms, so ; we also know that the speed of the horse is 5 meter/second, so . Lets replace those values in our formula to find :




J

We can conclude that the kinetic energy of the horse is 6250 Joules.
