1. A student pulls a block across a rough surface at a constant velocity. The student pulls with a FP force Fe that is at an angle O above the Factor horizontal, as shown. a. (SEP4 - Graphs) On the dot, draw an FBD Fipx 106 for the block. Be sure to label any forces 10 that are equal. 10 10 Then the student adjusts the way they are pulling so that the magnitude of Fr doesn't change, but the angle O is decreased. b. (SEP5 - Math) State what happens (increase, decrease, or stay the same) to each of the following forces 10 -12 when the block is pulled at the smaller angle but the same size force. Use equations to support your answer and give a short explanation as needed. i. Fe ii. FN
