1. How fast (in rpm) must a centrifuge
rotate if a particle 8.00cm from the axis of rotation is to experience an
acceleration of 125,000 g’s?

2. Highway curves are marked with a
suggested speed. If this speed is based on what would be safe in wet weather,
estimate the radius of curvature for a curve marked 50 km/h. Use Table 5 1.
