2) A child applies a force F to a 15 kg sled moving on the frozen surface of a frictionless pond. Fx, the x-component of F, is parallel to the pond's surface. As the child controls the speed of the sled the Fx she applies varies with the x coordinate of the sled as shown above. At x = 0, the sled was moving in the positive x direction at 2 m/s. Find the following. a) The speed of the sled at X = 10 m b) The speed of the sled at X = 20 m F, (N) Kota 5 10 15 20 3 0 -3-- 25 30 35 x (m) 2) A child applies a force F to a 15 kg sled moving on the frozen surface of a frictionless pond.
