I did get (r) max / (r) min. IT was equal to 0.95. I just forgot to show that i square rooted both sides in the above posts. I fixed that though.

A woman stands on a scale in a moving elevator. Her mass is 60.0 kg, and the combined mass of the elevator and scale is an additional 815 kg. Starting from rest, the elevator accelerates upward. During the acceleration, the hoisting cable applies a force of 9410 N. What does the scale read...

is my value correct though? 0.95 ?

thanks.

Is this correct? May someone go over it. Is my logic correct? I guess since Fg is inversely proportional to radius, then if Fg is 11 % larger, the radius must be a portion smaller ?

Ok so it would be: 1/r^2 (max) = (0.11)/r^2 + 1/r^2 so it would be: 1/r^2 max = 1.11/r^2 min cross multiplication would give me: (1.11)r^2 max = r^2 min Since we need the ratio of r^2 max to r^2 min divide both sides by r^2 min. 1.11 r^2 max / r^2 min = 1 now divide both sides by 1.11 r^2...

As a moon follows its orbit around a planet, the maximum gravitational force exerted on the moon by the planet exceeds the minimum gravitational force by 11%. Find the ratio (r)max/(r)min where (r)max is the moon's maximum distance from the center of the planet and (r)min is the minimum Ok...

1. At a time when mining asteroids has become feasible, astronauts have connected a line between their 3500-kg space tug and a 6200-kg asteroid. Using their tug's engine, they pull on the asteroid with a force of 490 N. Initially the tug and the asteroid are at rest, 450 m apart. How much time...

Thanks a lot guys! I had also thought that because they both end up hitting the ground, their velocity becomes zero. Thanks!

Here is the problem that I am having trouble with (It probably is a no brainer, but i am a bit rusty- not a bit actually, a lot!). Here is the question: A student stands at the top of a building to perform a kinematics experiment. He throws a red ball directly upwards with an initial speed...
