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.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
