2.5 Concrete mixer* In a concrete mixer, cement, gravel, and water are mixed by tum- bling action in a slowly rotating drum. If the drum spins too fast the ingredients stick to the drum wall instead of mixing. Assume that the drum of a mixer has radius R = 0.5 m and that it is mounted with its axle horizontal. What is the fastest the drum can rotate without the ingredients sticking to the wall all the time? Assume g = 9.8 m/s.
