Introduction: Static friction

More Details: A 4.0-kg toboggan rests on a frictionless icy surface, and a 2.0kg block rests on top of the toboggan. The coefficient of static friction between the block and the
surface of the toboggan is 0.60, whereas the kinetic friction coefficient is 0.51. The block is pulled by a 30 N- horizontal force as shown. What are the
magnitudes and directions of the resulting accelerations of the block and the toboggan?
