A runner exerts 2,000 j of work while traveling 10 m along a horizontal stretch of track. what average force was exerted by the
maria [59]

The average force exerted by the runner is 200N.

A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

When a force is exerted across a distance to an item, work is accomplished. This implies that the total energy of an object will be impacted when a force is applied to it over a distance.

Work = Force x Distance

Force = work / distance

Force = 2000 J / 10 m

Force = 200 N

Hence, the average force exerted by the runner was 200N.

To know more about force refer to:

Explanation:

Liquefaction is a phenomenon in which the strength of the soil weakens due to the earthquake or any other load. The solid behaves like a liquid. Liquefaction of soil below structures cause lot of damage during Earthquakes.The soil looses stiffness due to seismic waves and water.
