Plzzz someone help me 1)Why does an object that is sliding across carpet slow down?

2)Compare an object sliding across carpet and that same object sliding across a bare floor. Why is the object quicker to slow down on carpet than on the bare floor?

1) The object slows down due to kinetic friction.

2) The coefficient of kinetic friction is higher on a carpet than on the bare floor, therefore the object would slow down quicker on the carpet

i just copied the other one for pts sry

Projectile Motion:

An object or particle that is thrown near the Earth's surface experiences a projectile motion and creates a parabolic path. Its velocity at each point or time t is expressed as the sum of horizontal and vertical components. The horizontal velocity is constant while the velocity along the y-axis is affected by the gravity.
