*17-48. The snowmobile has a weight of 250 lb, centered at Gj, while the rider has a weight of 150 lb, centered at G,. If h = 3 ft, determine the snowmobile's maximum permissible acceleration a so that its front skid does not lift off the ground. Also, find the traction (horizontal) force and the normal reaction under the rear tracks at A. 0.5 ft 1 ft F1.5 ft-
