Launch Time: The Physics of projectile motion experiment NEED HELP Launch Time: The Physics of projectile motion experiment NEED HELP I am have a hard time understanding what I need to do. In the project it gives equations and one of them is finding the initial velocity so I can predicts the points on the table. I have a lot of the other variables but am having a hard time finding understanding how to do this. I have m=2.7g, r=22.1 cm, L=24.3cm, l=1.1*10^-3 kg*m^2, x subscript 0= 8.382cm, and… Read more

Maglev Train Maglev Train Does the 90° molding have to be clear plastic for the walls of the Maglev Train project? While searching it has been hard to find this at a decent price. We are able to find black plastic, white plastic and wooden molding all that fit the other requirements of 3/4 inch in-depth. Re: Maglev Train It doesn't need to be clear plastic, the clear plastic is just nice because you can see the train floating above the track from the side.
