A block of mass m is given an initial velocity by the spring. The spring has a spring constant k, and is squeezed 0.200 m when the block is at point A. There is no friction in the system EXCEPT for between B and C where the slope has friction coefficients s and pak. The block goes around the circular loop of radius R and is in contact with the loop all the way. The distance between B and C is e (e > 2m). Assume the size of the block is small compared to R. The vertical position of C is the same as the center of the loop. For velocities: let Va, Vg, Vc, and Vo = the velocities of the block at point A, point B, point C, and point D respectively. Set the gravitational potential energy Ug = 0 at the elevation of point B. R C Give your answers in terms of: the given quantities, known constants, and you may define and use E, if needed. 1.
