hi! I too require help. I got as far as: 5+5cos(2\Theta) = 15sin(2\Theta) + a I'm not sure how to solve this :/

The car we used was flat so during the crash in the air, there are no forces? What about when he hits the ground & roles (since he isn't human). I think he means in the air, but I already sent my teacher an email asking which, I'm waiting for him to get back to me. I uploaded the graphs which...

Homework Statement Ok so we did an experiment in class. We took a wooden board, and put it on an incline. We put a car on top of the board with a man made of play-doh. We put a barrier on the board so that the car would crash and the man would fall off. This has to do with the topic "why do...

Should i call up McGraw-Hill Ryerson? When i ahve physics next i'll come back here and post the answer and i'll come back if I have any further break thoughts. Thanks for your help so far. (btw, originally i agreed with your final answer :P)

It asked how would it affect the speed? If I go by your belief that a) & b) are amplitude then in c) the speed doubles. If I go by my belief that a) is wavelength then both a) and c) have twice the speed while b) is amplitude and doesn't affect speed.

going by what you think, only c) and it would double. From the way i understand it a) & c) would. also another important formula V=(lambda) / (Period)

I think pulse size = wavelength and energy = amplitude. From what i understand now at least. (not positive)

i understand that now, thanks :) For a) (only one i don't get) if the pulse size increases, is that where the frequency decreases. because frequency and wavelength are inversely proportional.

Homework Statement "After a transverse ware pulse had traveled 2.5 m through a medium, it has a speed of 0.80 m/s. How would this speed have differed if: a) the pulse had been twice the size? b) the pulse had had twice the energy? c) the pulse had traveled twice the distance?" Homework...
