Wow! Thank you for all of your help I would have never of thought that mass did not matter. now I don't have to spend a week constructing an object Thank You:biggrin:

mass does affect the time so the heavier the weight the better and what do you mean by slider? Thank you for all of your help

I don't clearly understand your question but the ramp is wooden and if an object slides it will create a lot of friction so i believe roll down is the answer?

Thank You, So far I tried racing a hollow pipe and a pipe filled with weights with the exact same radius. The pipe filled with weights won. Because making objects takes a lot of time and my time is limited I want to know what will go faster... Object A Plastic object completely filled 5 inch...

Well...The point of the competition is to win and i doubt a marble will win the contest unless it is 5 pounds. Reaching the bottom in two turns is not the objective its just a rule to limit the size of the object the objective is to have the fastest overall object. With that said do you think a...

Homework Statement I have this Physics Contest where you have to create an object that will roll down a 6 feet ramp which is positioned at a 7 degree angle above ground. The object can not have more than one contact with the ground(For example you cannot have two wheels touching the ground...

Thank You

One last question. He used a sling shot so i assume the eraser is f;lying down the hallway. I did not see how fast it was going so how do i know how fast i should slide it along the floor.

I am really sorry for not being clear enough and wasting your time. The teacher did the lab outside so we could not see how long it took the eraser to move or how far the eraser went. When he came inside he said the initial velocity is 13 and he told us to find a formula and predict how far the...

The instructor is shooting the eraser on the floor in the hallway. So the angle is 180 degrees right? but he shoots the eraser forward horizontally he does not drop it. Also we don't know how long the eraser travels on the floor. Is their a formula to solve this problem with just the initial...

Homework Statement We are doing a lab where the teacher took an chalkboard eraser and he put it between to rulers in a hallway. He used some sort of slingshot to project that eraser.( we did not see how far the eraser went) We have to find how far the eraser will travel in meters. All we were...

Yeah for part e. he was asking if it was a straight line or not and the slope was 23. Thank You for your help

Homework Statement A spring has a force sensor attached to it and is pulled at increasing distances from rest. A reading is recorded on the force sensor and the data is plotted below. Plot data on Excel x (m) Force (n) .005 1.9 .010 2.5 .020 3.4 .030...
