Mass movement choose one: a. happens only when the slope of a hill gets steeper than the angle of repose. b. can't happen underwater because the buoyancy force of water is too great. c. is more likely to happen under dry conditions than under wet conditions. d. is a gravity-driven downslope movement of natural materials.

Aracecar driver has to hold on tightly when going around a banked curve. approximately what is the centripetal force on a 2220.0 kg car going around a circle with a diameter of 190.0 meters at 25.0 m/s?

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
