the answer would be B) Planet B because it has the greatest mass/radius value in comparison to the other options

But even considering that my answer of E) Planets B and D is correct right?

Can someone please verify if my reasoning is accurate? I chose E) Planets B and D because they both have the same ratio of mass to radius which is the lowest of all the other planet options. Due to the fact that they have mass and radius evened out the gravitational pull will pull weight down...

Thank you all, I will converse with my instructor regarding my reasoning.

As per the information given in the problem the orbits will be of the same speed in the same circular orbital path?

I need help with understanding this problem. I had initially chosen B, that the two satellites had the same speed because the mass does not effect the velocities of each of the satellites considering they are in orbit. But that answer was marked incorrect by my instructor. What other answer...

When I turned in that answer, it was still wrong.

So this is only a conversion problem? Thanks you very much.

53 rpm equals 5.55 rad/sec multiply 5.55 by 2pi to get angular velocity of 34.8717 Is the answer 34.8717? What should I have done to more accurately solve the problem with a better understanding? What other steps should I take when solving similar problems? and lastly, Is the mass relevant...

decreasing gravitational potential energy

How come elastic potential energy will not decrease as the mass goes down?

Assuming zero spring mass and zero friction, At the greatest value of x, the loss in gravitational potential energy should equal the loss in elastic potential energy. so I did (1/2)kx^2=mgx to isolate x in the formula, x=(2mg)/k then I plugged in my values so: (2*13.6*9.81)/8.8= 30.3218...

I tried the problem again using sin instead of cosine. work done= force x distance moved in the direction of the force. The vertical height fallen is 3sin28 so work = change in gravitational potential energy = mgh = 4 x 9.81 x 3sin28 = 55J does this seem more right than my previous answer?

It would be the complementary angle to 28 degrees, so 62 degrees

theta would be 28?
