    Calculate Vertical Loop on Roller Coaster for 5G Limit

    Hi, part my project involves designing a vertical loop on a roller coaster that is not to exceed 5 G. The weight of the coaster is 4.5 x 10^4 N. But, I don't know how high I need to start the coaster so that there is enough mechanical energy to make it through the loop. I read online that the...

    Calculate Speed at Top of Roller Coaster 2nd Hill (5.5m)

    The mass of the coaster is 800 kg The lift hill is 18 m highabd it goes up the lift hill at 2.50 m/s The second hill is 5.5m high. Wants to know the speed at the top of the second hill. do i really care about the weight of the car? This is what i have so far PEtop1 +KEtop1 = KE bott...

    Questions about roller coaster physics

    Hello, I'v lately been intrigued by roller coasters as of late (notice my prior post about that app) I havnt been able to find any good websites to explain the physics of roller coasters in detail. I know of-coarse that it works on conservation of energy, that the initial potential energy is...

    Energy conservation on a roller coaster

    Assuming the roller coaster is towed to the top of the hill on the left-hand side of the diagram and released. How would the conservation of energy work. I know that at the top of the first hill there would be P.E. and as it gradually rolls down the K.E. takes over. But how about as it...
