I've been looking at this question for about 1 hour now, and cannot figure out the relationship between the distance an object is at the bottom of the ocean vs. its area... The question is: A solid copper ball with a diameter of 3.20 m at sea level is placed at the bottom of the ocean, at a...

Yeah... I didn't understand that there was an upward componenet of tension that reduces the normal force. Thanks! :)

I thought that the natural reaction force is just mass*gravity?

i am still coming up with the wrong answer...

I have a similar question in my book, but they use 20 degrees, 18 kg and a distance with 20 m with the same kinetic coefficient... I solved for T=18/cos20 and came up with the wrong answer... the answer they have in the back of the book is 79.4N

It's cool... so I came up with f(kinetic)= .5*17*9.8 and then made that to equal Tsin19.5+Tcos19.5 and then solved for T... am i on the right track?

But the sledge is horizontal to the ground while the rope is the only thing inclined at 19.5 degrees

So what equation would I use to go about finding the tension?

I thought I could use that equation to get the sum of all forces and solve for T (tension)

The problem is: A sledge loaded with bricks has a total mass of 17.0 kg and is pulled at constant speed by a rope inclined at 19.5 degrees above the horizontal. The sledge moves a distance of 21.0 m on a horizontal surface. The coefiicient of kinetic friction between the sledge and surface is...
