Homework Statement Table 5-2 gives the mean distance, period, and mass for the four largest moons of Jupiter (Those discovered by Galileo in 1609). A) Determine the mass of Jupiter using the data for Io B) Determine the mass of Jupiter using data for each of the other three moons. Are the...

Can I ask what the component method is?

I know that but I need to have a set of coordinates to go with it, like 40 degrees North of West. The answer is in the back of the book but my teacher needs to see work. I can't figure out how I can find the angle and length. Lewando: Everything has to be done with math. My teacher says that a...

Homework Statement A passenger on a boat moving at 1.5m/s on a still lake walks up a set of stairs at .5m/s. he stairs are angled at 45 degrees in the direction of motion as shown. What is the velocity of the passenger relative to the water. Homework Equations The Attempt at a...

Homework Statement Romeo is chucking pebbles gently up to Juliet's window, and he wants the pebbles to hit the window with a horizontal component of velocity. He is standing at the edge of a rose garden 8m below her window and 9m from the base of the wall. How fast are the pebbles going when...

Homework Statement Graphically determine the resultant of the following three vector displacements: 1) 24m, 30 degrees North of East 2) 28m, 37 degrees East of North 3) 20m, 50 degrees South of West Homework Equations The Attempt at a Solution I have the vectors drawn but I...

Homework Statement I can only attach one file So I will put a link to flickr. http://www.flickr.com/photos/25742963@N04/sets/72157631801173637/ Homework Equations A avg.= delta v / delta t x=v^2/2a t=v/a The Attempt at a Solution I have to do these problems for homework and...

I completely understand what you are saying, I am a black belt in karate, I just wanted to do this for its and giggles. See if the accelerometer measurement was any accurate.

Well I am trying to figure the speed at which somebody would be hit, so I am thinking that the deceleration from my arm would be almost equal to if not less than from hitting a person. I am kind of missing you on the square root thing, do you mean I need to take the square root of 2ad? Because...

You could also drill out some of the core material in the wheel to make it lighter, and the smaller a wheel is the more rpm's it will make to go the same distance as a larger wheel, which means more friction against the bearing inside. You could reach higher potential speeds with larger wheels...

It said that it experienced 8.5 g's. I assumed that vi was 0 and that my arm travels about 26 inches. I converted everything into m and calculated it and got 110 m/s as vf. Then did f=ma and got 74 n or ~168 ft. lbs of force. Oh and I said that my arm was about 15 lbs or 6.8 kg, which is...

Hey guys I am a high school senior and this is my first year taking physics. I am really interested in the subject and like to find out real world problems for fun. One of the things I am trying to do is find my punching speed. I downloaded an acceleration app for my phone that displays the...
