testing if i can put the image on this post. http://img222.imageshack.us/img222/6819/physicszw2.gif

not sure, maybe the extra line on the equal sign just means that it's not just a number answer but also with units.

there's no difference, it just means average velocity is equal to change of distance divided by change of time.

Hello, I am currently in beginning physics and we are learning a lot about Trig onometry. A homework problem is really bugging me. Here's what it says: Find the angle A, given the altitude and arc length of the figure shown: (the picture is in the attachment and also some work i have done.)

the deltaX or distance is 10.0cm(the thickness of the board) minus 2.00cm(the length of the bullet) because you assume that the bullet only accelerates when it's head is in contact; you put .05 instead of 8 when you plugged it in.

so is the acceleration on Zelth .16m/s^2 and my weight on Zelth is 7.9N?

oh, i get it now, you're the coolest berkeman!

do one problem first, then the other, don't go back and forth. Convert the different units into the same one, either mile into yd or yd into mile. Use the formula V=D/T to find the student's initial velocity and then use the formula D=ViT+1/2AT^2 to find the acceleration. If you still can't...

Also, I know that the acceleration due to gravity on Earth is 9.8m/s^2, but how can I use F=ma to find the mass of the Earth?

I found that 1 Newton is equal to about .102 kilograms, so If I weigh about 50 kg, my weight in Newton on Earth would be 500N, and if I converted it from N to kg on the planet Zelth, I would weigh over 3000 kg. Is this right?

I found that the average height of rain clouds are above 1000 meters and the formula: Vf^2=Vi^2+2AD would find the final velocity of over 140 m/s but I'm not sure if water could hurt people.

'weird question, I think he\'s trying to ask sort of the X-Men, Rogue\'s special ability or something. Obviously we get energy from food and heat from light etc. and all it takes is nothing but what we usually do. However, if you mean absorb a lot of energy like the fictional character, then I...

My teacher gave us these extra credit problems and I couldn't really solve them. Here they are: "If air resistance did not exist, would rain be dangerous? Why?" "On the imaginary planet Zelth, a 100 kg mass weighs 15.8N. What is the acceleration due to gravity on Zelth? How does it compare...
