#### Answer:

#### Explanation:

Since the object is moving on a plane surface, the kinetic friction experienced by the object will be

So, using the third kinematic equation

The object is said to have come to a halt so that means

So,

So, we know it travels a distance of

So,

So,

Solving it yourself, you now understand that things look odd even if they are right.
