Asolid 0.4550 kg ball rolls without slipping down a track toward a vertical loop of radius r = 0.6750 m . what minimum translational speed v min must the ball have when it is a height h = 1.021 m above the bottom of the loop in order to complete the loop without falling off the track? assume that the radius of the ball itself is much smaller than the loop radius r . use g = 9.810 m/s 2 for the acceleration due to gravity.

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
