Logic test!

[rbgarr]

A bat and ball cost $1.10. The bat costs $1 more than the ball. How much does the ball cost?

Correct answer to come later....

[P.I. Stazzer-Newt]

BAT $1.05
Ball $0.05

[Joe (SoCal)]

The ball costs 5 cents

Edit to add: this once again shows that this is the smartest place on the net

[Jim Bow]

Your prices are from 1940. Current bat cost is $37.99. Go from there.

An oldie, but still a goodie for showing the distinction between Fast and Slow thinking.

Or a basic exercise in AlGebra.

Can you show your work, PM?

[Peerie Maa]

Yep, it is right there in front of me on a piece of paper.
Do you want me to scan it for you?

I normally save the construction of equations for those problems too complex to do in my head. It's an invaluable tool, at need, but an intermediate step that is sometimes superfluous. Of course, some mad blokes ENJOY that process. Until the 12-step program for that particular issue is fully developed and beta tested... I guess we'll just have to leave them to it <G>

Price of a ball: x
Price of a bat: x + $1.00

Price of ball and bat: x + (x + $1.00) = $1.10

x + (x + $1.00) = $1.10
x + x + $1.00 = $1.10
2x + $1.00 = $1.10
2x = $0.10
x = $0.05

[Canoeyawl]

This is as difficult as deciding whether to vote for Warnock or Walker

[George Jung]

Oh, I dunno... I'm seeing complete agreement!

just a different logic test

[Ralphie Boy]

Which weighs more, a ton of feathers (let’s say a Metric Short Ton), or a ton of bricks?

[Peerie Maa]

Which weighs more, a ton of feathers (let’s say a Metric Short Ton), or a ton of bricks?

Neither, you silly Ralphie Boy.

[robm]

What is a metric short ton?

1 short ton = 2000 lb
1 long ton = 2240 lb
1 tonne = 1000 kg.

Pardon me, I am a units nerd. Don't get me going on about the various gallons....

[Ralphie Boy]

Doh - It should have been either a Metric or a Short Ton! My bad! I forgot people actually know stuff here!


OK, OK, what about this: You are on the moon and drop a brick and a feather from the same height, which one hits the moon dust first?

[robm]

Simultaneous - no air resistance.

I used to get in trouble for not showing my work. To me, the answer was often so obvious I just could not imagine any work was required.

The biggest vacuum chamber in the world is at NASA's Space Power Facility in Sandusky, Ohio. it's 100 feet in diameter and 122 foot tall, and can pull a vacuum better than 4×10^–6 torr (0.00533289474 pascals or 0.00000157498368 inches of mercury).



You can guess what a physics professor can do with a place like that:

Are we to include the electrostatic effects of Moon dust in our responses?

Physics is a bit harder than that.

If the center of masses are at the same "height", the orientation of the brick and rock will matter.

If the center of masses are at different "heights", the gravitational attraction will be different on each.
