Here is one of my physics homework problems I have to do:

An unusual variant of basketball is played on the planet Zarth. During the game, a player flies above the basket and drops the ball in from a height of 14.3 m.

If the ball takes 4.7 s to fall into the basket, what is the acceleration due to gravity, g, on the planet Zarth?

gotta love my physics teacher















































so what's the answer

is this a trick question?

Physics sucks ass.


I really don't know Physics wasn't my strong point.

My Physics diploma exam is tomorrow.

that answer does not compute borg

I've seen stranger. I had one physics teacher that themed an entire test around LotR.

The problem is unslovable (b/c I'm not going to go find my kinematics stuff right now)

I would have failed

Oh no, it's solveable. We turn it in to this website that tells us whether the answer is correct or not. So that means there is an answer...

mhm yes you would have

it should be initial velocity- final velocity/ time or somehting, i forget my pohysics equations

Vf2 = ViT + at^2

You made my brain hurt cry



i'm pretty good at math.. but i can't help you there srug

is the final velocity squared hmm

I couldn't answer it, with my knowledge I'd need another information, the Potential Energy for example. Or the mass.

So which one?

Gaaah, it's now been...4 years since I've had physics. Damn.

I don't remember but it's easy to figure out. Gravity is meters per second squared, remember.

My physics teacher used to write his students into the test. It was great. There was a question on one of the tests about how I had thrown my book off a bridge, and given the velocity and height of the bridge off the water, we had to figure out how far away it would land.

I loved my physics class

It's all the information I'm given. shrug

Though Mr. Bacon is right. I couldn't calculate final nor initial velocity though.

doh gah!!! m/s/s I always forget to put that...

although I'll still need the answer...

so what's the answer

eww...

I guess you can take the average velocity.

I got: 0,64735174287007695789950203712087


Whichs ounds slightly reasonable.

You mean 0.64735174287007695789950203712087 right?

I got 1.294703486 m/s/s

Originally posted by AOR
I got 1.294703486 m/s/s Well, maybe, how did you calculate it?

I think

a = Average Velocity/time

Average Velocity = 14.3 m / 4.7 s

Time = 4.7 s

But I might be wrong.

They give you DeltaX-14.3 and they give you T-4.7

The formula is X=.5gt^2

So pluggin it in I got 14.3=.5g(4.7)^2

Isolating the "g" I got 1.2947...*plugs it into computer program* and I'm correct w00t

you need the formula with distance, i forget it

It's one of the free falling equations

see:

Yes, that makes sense.

Oh, I see I forgot to take it times two. Well close, though not good enough.

Here's another, not as funny but really hard:

Tina the ballerina leaps into the air during her dance practice.

How long does she remain in the air if she jumps straight up with a speed of 1.71 m/s?

EDIT: It uses the second eqution realizing that vf=-vi

I sure hope he's imitating a seal. 13

Oh he is flirt

Initial velocity is always zero, it says he drops the ball, hence it starts from a stationary point (his hands). If he threw the ball or something, it would be different.

Also, you are given a height measurement, so use the equation with displacement, rather than one of the others, since you dont have a final velocity or acceleration.
