A block of mass M is at point A on the slope (the slope is just a %u201Cregular roller coaster ride%u201D and the shape does not matter. Take the system to be a single object block). There is no friction and the the starting velocity of the block is 3.0m/s upslope. What is the velocity at the bottom of the slope at point B which is 5 meters below point A.
Three deer, A, B, and C, are grazing in a field. Deer B is located 64.4 m from deer A at an angle of 53.8 ° north of west. Deer C is located 76.2 ° north of east relative to deer A. The distance between deer B and C is 96.8 m. What is the distance be..
