9. A group of Glenview youngsters went sledding. Lee Mealone was frustrated with the group and began to run ahead. As he pulled his 11.0 kg sled, he applied a horizontal force of 14.0 N (rightward). The coefficient of sliding friction (mu) between the the snow and the sled is 0.10. To receive credit: Draw a freebody diagram for the sled. Use appropriate force symbols to label the type of each force acting on the sled. Determine the acceleration of the sled. If the sled is accelerated from rest, determine its velocity after 3.2 seconds. Please circle, box, or underline your answers. PSAYW
