A cart with mass m1 stands on an inclined plane at angle alpha. The cart is attached to a mass m2 by a massless string. This gives:
m2*g*sin(alpha)=(m1+m2)*a, where a is the acceleration of the car.
How can a(alpha) be determined from this?
Thank you

We have the following problem: We need to determine the mass of a proton as it exits the HERA particle accelerator. Given the entry velocity of 0.99973*c with an energy of 40 GeV, the exit energy of 920 GeV, and the rest energy of 938.27 MeV/c^2. It wasn't a problem at the entry point, since…
Hello, For example, I am away from home for a year and have 20-30 electrical household appliances, including 20 1kW TVs. The appliances are switched off, but the power plugs of the appliances are still plugged into the sockets. How much electricity will they use after one year? Or how much would that cost per…
You can resolve the equation according to sin(alpha).
From the sine you get the associated angle

Just change the equation to a?
So: a(alpha) = (m2*g*sin(alpha)/(m1+m2)?
Yes, if the equation is correct. Can you check Alpha to 0° or set 90° and see if a meaningful acceleration comes out.
