Suppose an object’s initial velocity is 10 m/s and its final velocity is 4 m/s. mass is constant.

what can best be concluded about the object based on the work-energy theorem?

The negative work done states that the work is done by the object and not on the object.

Explanation:

According to work energy theorem, the work done is equal to change in kinetic energy exhibited by the body. As the mass of the object is constant, and the velocity is decreased from 10 m/s to 4 m/s, the work done will be

Here W is the work done, m is the mass and v is the final and u is the initial velocity of the object. As the initial velocity is greater than the final velocity. So

So the work done is negative for the given situation. The negative work done states that the work is done by the object and not on the object.

idk sorry i only needs point for apex

explanation:

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
