You can't determine the force acting on an object with just its mass. You need the acceleration as well.

Here's why:

* Newton's Second Law of Motion: This law states that the force (F) acting on an object is directly proportional to its mass (m) and acceleration (a). The formula is:

F = m * a

* Missing Information: You've provided the mass (m = 65 kg), but you haven't given the acceleration (a). Without the acceleration, you cannot calculate the force.

To find the force, you need to know the acceleration of the object.

Let me know if you can provide the acceleration, and I can help you calculate the force!
