This is another problem a buddy of mine and I cannot figure out if our life depended on it. Here's the question word for word:
A roller coaster track has a hill with a circular curve of radius 20 m. Find the speed of the roller coaster at the top of this hill.
Started by drawing a picture and writing down the given radius. Then we hit a wall.
Our first thought was how can we figured the speed of the roller coaster by only having the radius of the curve? We're looking through all our equations for this chapter and a couple integrate velocity and radius. Such as; v = 2(pie)r/T (T is the period); Ac = v^2/r; Fc = mv^2/r
Each equation have at least 2 unknowns. We hit another wall with these equations.
Please offer any kind of suggestions. Our ears and eyes are wide open.
TIA, Bryan
