nevermind i figured it out myself...thanks

that won't work for the first question...the object is a spaceship and there is nowhere in that equation to plug in its mass...

1) if something is 5 Earth radii above the Earth's surface and you know its mass, how would you figure out force of gravity on it? 2)and given the radius and mass of a planet how would you be able to figure out the acceleration due to gravity on it?

sorry...jeez...figured it out myself anyway...

Question: how would i find the coefficient of static friction that would keep people from falling out of a spinning amusement park ride when the bottom dropped out if all i knew was the radius and the amount of revolutions per second...?

nevermind, i figured it out myself...thanks

a 27.5kg box is connected to a 13.75kg box on a frictionless pulley. my question is if you calculate the acceleration does that include horizontal and vertical acceleration, and if so, how do you just find the downward acceleration?

thanks...i'm sorry i didn't see the link that you put up there...thanks so much...i was able to get the answer, but those equations are a little beyond where we're at right now...thanks again.

and how did you happen to change the numbers around so that they were identical to a problem in my textbook?

the answer to the problem you wrote is actually 4.1 meters but i don't know how that answer was reached

it's a different problem...that's all the info I've been given...i don't know how the speed factors into the problem...i don't know the object's weight or anything else

thx that helped...i actually figured it out on my own...

If the coefficient of kinetic friction of a box is 0.23, how would you find out how far the box would travel with an initial push of 4.2 m/s? Assume the "push" has already happened.

how do you figure out horizontal force necessary to move an object if the coefficient of kinetic friction is zero?

Thanks everyone for helping with my last question. Here's another one...(I'm actually in a Physics class, not just asking for "s and g." My TA for the class doesn't have a clue what she's talking about.) A rock is thrown off the edge of a sea cliff. 3.2 seconds later you hear the sound of...
