No it is not what I meant. also none of what you have written is what I intended. Let me be perfectly clear: v' = m1 / (m1 + m2) * v1 This is the equation I attempted to use, NONE of these equations are giving me the correct answer. The chapter is on elastic and inelastic equations...

Homework Statement I have tried this several times, though I am going wrong someplace along the way. I have tried using these equations below but I cannot seem to get anywhere with it. I left the attempts below so that you may see what I have done, and maybe someone can tell me what I am doing...

Ok that took care of it, Thank you so much!

I guess I am just unsure of how to do the problem?

I was able to solve it, thank you. I was leaving out the exponent on the radius, causing the calculation to be wrong.

Homework Statement Astrology, that unlikely and vague pseudoscience, makes much of the position of the planets at the moment of birth. The only known force a planet exerts on Earth is gravitational. (a) Calculate the gravitational force exerted on a 5.00 kg baby by a 130 kg father 0.200 m away...

Homework Statement What is the ideal speed to take a 70 m radius curve banked at a 30.0° angle? Homework Equations tan θ = v2/r g The Attempt at a Solution This has me stuck, when I attempted this I came to the equation v= √ g*r* tan Θ But when I substitute in the variables, I enter then into...

okay, and sorry I meant multiply not divide. Thank you that helped me to the right answer, greatly appreciated!

Yes if I am not mistaken it is the formula C = 2*π* Radius? So, I find the circumference of the Earth first? I am confused about what I do with the circumference, do I then divide it by the age of the earth?

Homework Statement Taking the age of Earth to be about 4 ✕ 109 years and assuming its orbital radius of 1.5 ✕ 1011 m has not changed and is circular, calculate the approximate total distance Earth has traveled since its birth (in a frame of reference stationary with respect to the Sun). It is...

That was exactly the problem! Thank you so much!

Homework Statement A fairgrounds ride spins its occupants inside a flying-saucer-shaped container. If the horizontal circular path the riders follow has a 8.00 m radius, at how many revolutions per minute will the riders be subjected to a centripetal acceleration 1.95 times that of gravity...

okay great thank you!

Homework Statement Semi-trailer trucks have an odometer on one hub of a trailer wheel. The hub is weighted so that it does not rotate, but it contains gears to count the number of wheel revolutions—it then calculates the distance traveled. If the wheel has a 1.02 m diameter and goes through...
