a.) Determine the optimum inclination angle for a 520 foot radius turn where traffic is expected to travel at 55 mph, to the nearest degree (deg).
b.) A mass swings in a circular path while attached to a 15.8 m length rope of negligible mass. The rope makes angle 25.0 degrees from vertical. Find the Speed of the mass as it orbits, in m/s.

niform circular motion has a uniform speed v and carries an acceleration v-sq/radius such that the direction would change to give a circular path or trajectory raction for the case of satellite, contact force for the case of roller coaster, a string tension acting on a circulating blob, holding etc. The force to maintain the acceleration or the force causing the acceleration could be gravitational 6.67E-11 N meter-sa/ kg-sq Gravitational attraction F Gm1m2/distance/distance with G Kinetic equation vf'vf vo v+2a...
