Solve the following problems using the GUESS method and correct significant figures. Answer in complete sentences where appropriate. Be sure to show ALL work! 1. In the diagram below, a 10. - kilogram block is at rest on a plane inclined at 15 to the horizontal. 10. kg As the incline is increased to 30. , the weight of the block will (A) increase (B) decrease (C) remain the same 2. A 39 kg rubber block is pushed up a dry concrete ramp inclined at 32 by applying a force of 231 dia newtons parallel to the incline. Draw a free body diagram. a. Calculate the weight of the box. Block b. Calculate the parallel component of the weight. c. Calculate the perpendicular component of the weight. d. Calculate the force of friction acting on the box. e. Calculate the net force acting on the box. [Hint: consider ALL of the forces acting along the plane of acceleration.] f. Calculate the acceleration of the box.
