Answer 2

Answer:

The work done will be negative.

Explanation :

• Work is defined as the energy that is applied to or removed from an object by applying force along a displacement.
• Work is the dot product of force and displacement.
• It is frequently described in its most basic form as the result of force and displacement.
• Energy manifests mechanically as work.
• The joule (J), or newton-meter (N m), is the accepted unit of work.
• When force and displacement are directed in opposing directions, the work completed is referred to as negative work.
• When force and displacement are in the same direction, the work performed on an item is referred to as positive work.
• When force and displacement are perpendicular to one another or when either force or displacement is zero, the work done is said to be zero work.
• When the runner is moving and is facing a wind from the opposite direction. The direction of force and displacement is opposite. Hence, the work done will be negative.
