Zak pushes her with a force of 125 \rm N over a distance of 1.00 \rm m. If her mass is 20.0 \rm kg‚ what distance d_2 does she slide after Zak’s push ends? Remember that the frictional force acts on Greta during Zak’s push and while she is sliding after the push. F= Fp-Fr E= F*Lp= (Fp-Fr)*Lp= Fr*Lr Lr= Lp*((Fp/Fr)-1) Lr= 1*((125/(20*9.8*0.25))-1)= 1.6 m Mark pushes his broken car 150 m down the block to his friend’s house. He has to exert a 110 N horizontal force to push the car at a constant

The Impact of War and Conflict on Public Services All of war and conflict impacts heavily on public services. This is especially true for the armed services as they are usually on the frontlines when it comes to trying to resolve conflict and bring peace.

Ranging from ages of 8 to 15‚ child soldiers are raped‚ abused‚ and sometimes even sent on suicide missions if they haven’t died from the hardship put on a child in the military. 40% of child soldiers are recruited by force and many times forced to kill their family so that they don’t have anything to come back to if they escape from

The History of the “Grog Bowl” Formal military dinners are a tradition in all branches of the United States Armed Forces. In the Air Force‚ Navy‚ and Army it is the Dining-In; in the Marine Corps and Coast Guard it is Mess Night. The Dining-In is rich in tradition and the Dining-Out is similar in all aspects to a Dining-In. The major difference is that the Dining-Out includes spouses and guests. As with most ancient traditions‚ the origin of the Dining-In is not clear; formal dinners are
