Average Circ
Average Angle for estimating the speed?
A roller coaster reaches the top of the steepest hill with a speed of 3.0 km/h. It then descends the hill, which is at an average angle of 42^circ and is 35.0 m long. Estimate its speed when it reaches the bottom. Assume mu _{rm{k}} = 0.18. answer is in m/s
vi = 3/3.6 m/s
KEi/m = vi^2/2 = (3/3.6)^2/2 J/kg
deltaKE/m = gh = g*35*sin(42 deg) J/kg
vf = sqrt(2*(KEi/m+deltaKE/m))
I’m assuming that the friction coefficient can be ignored since the wheels can roll, and they can be considered massless since neither their mass nor moments of inertia are given.

Hoya 77mm Circular Polarizer HD Hardened Glass 8-layer Multi-Coated Filter $110.80 Light rays which are reflected by any surface become polarised and polarising filters are used to select which light rays enter your camara lens. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also saturate colors and increase contrast. Polarizers come in two variations but have the same effect. Linear polarizers work with older camera meter… |
