Base your answers to questions 150 through 153 on the following information and diagram. A block weighing 100. newtons is positioned on an incline that makes an angle of 30. with the horizontal. The magnitude of the friction force between the block and the incline is 10. newtons. A force of 120. newtons is applied by pulling on a rope that makes an angle of 30. with the incline, as shown. Horizontal 150 Draw a free-body diagram, and provide appropriate labels for each of the forces. [4] 151 Calculate the component of the block's weight parallel to the incline. [2] 152 Calculate the magnitude and direction of the component of the tension that is useful in moving the block up the incline. [2] 153 Calculate the magnitude and direction of the block's acceleration. [3] 43 The diagram below shows a sled and rider sliding down a snow-covered hill that makes an angle of 30. with the horizontal. Horizontal Which vector best represents the direction of the normal force, PM exerted by the hill on the sled? Horizontal Horizontal F V 30." N FN FN . .
