2. A glass beer mug has a mass of 1.3 kg when empty. You fill the glass with 0.7 kg of beer and slide it across a wet bar surface (no friction) while applying a constant force for 0.5 meters. The mug of beer is initially at rest but at the end of your push (you want to slide it to a thirsty customer) it is travelling at 1 m/s. a. What is the force you are applying to the mug of beer as you slide it for the 0.5 meters? b. What is the net amount of work that is done on the glass of beer during that push? c. What was the change in the glass of beer's kinetic energy? d. If the same force is applied, but you first spill out half of the beer, how fast will the mug of beer now be travelling after you push it again over the same distance of 0.5 meters?
