Hey, all, so I have been studying this problem all morning, and I do not understand two aspects to this example problem. I included a photo of the diagram used in this problem. You will see two cubes, but the diagram which corresponds to the problem below is the one on the right.PROBLEM: Find...

Alright, thanks for the link. But, I still don't know if this is correct, but I managed to get this. I added both vectors, giving me approx. 55 ft. Then I took the square root of that to get approx. 7 ft. I then subtracted 7 from 55 to get the answer: 48 ft. Is that the basic way of doing these...

Homework Statement A car travels 20.0 km due north and then 35.0 km in a direction of 60(degrees) west of north. Using a graph (that you must construct yourself as the book says... sorry for the inconvenience :/) and find the magnitude and direction of a single vector that gives the net effect...

Wait... is it 0? I tried doing it myself this whole time, but to no avial...

What do you mean by "draw all the forces on the sledge and get them to add to zero"? I'm lost.

Here's the problem: A sledge loaded with bricks has a total mass of 18.0 kg and is pulled at constant speed by a rope inclined at 20.0(degrees) above the horizontal. The sledge moves a distance of 20.0m on a horizontal suface. The coefficient of kinetic friction between the sledge and surface is...
