To increase the amount of electricity produced in the U.S., we could place what on top of all Wal-Mart stores?
Alecsey [184]

That's a great idea !  A wind turbine (windmill) or solar panels
on the roof of every WalMart, but don't stop there.  Let K-Mart,
Target, Sears, Macy's, 7-11, McDonald's, and Subway in on it too. 

In fact, why not place them on the roof of every house and
apartment building too ?

Just one question:  Who's going to pay for them ?
_________________________________________________

The biggest single year-round residential use of energy in the
USA is to heat up and keep a ready supply of hot water.  So the
single biggest residential use of energy could be eliminated with
a simple solar water heater on the roof of every house.  From my
own personal observation, I know that Israel is there now, but here
in the USA, it's apparently not worth the time, effort, or expense ! ? !

A hand pushes two blocks, A and B, along a frictionless table for a distance d. When the hand starts to push, the blocks are mov
Kitty [74]
  <span>net work = change in kinetic energy 

for Block B, we just have the force from block A acting on it 
F(ab)d= .5(1)vf² - .5(1)(2²) 
F(ab)d= .5vf² - 2 

Block A, we have the force from the hand going in one direction and the force of block B on A going the opposite direction 

10-F(ba)d = .5(4)vf² - .5(4)(2²) 
10-F(ba)d = 2vf² - 8 
F(ba)d = 18 - 2vf² 

now we have two equations: 
F(ba)d = 18 - 2vf² 
F(ab)d= .5vf² - 2 

since the magnitude of F(ba) and F(ab) is the same, substitute and find vf (I already took into account the direction when solving for F(ab) 

10-.5vf² + 2 = 2vf² - 8 
12 - .5vf² = 2vf² - 8 
20 = 2.5vf² 
vf² = 8 

they both will have the same velocity 
KE of block A= .5(4)(2.828²) = 16 J 
KE of block B=.5(1)(2.828²) = 4 J</span>
