A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has a 9.3 m radius, if the riders is subjected to a centripetal acceleration 3.1 times that due to gravity, what is the spinning speed in unit of revolutions per minute?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

A100 kg running back runs at 5m/s into a stationary linebacker. it takes 0.5 for the running back to be completely stopped
