(13%) Problem 3: Suppose two children push horizontally, but in exactly opposite directions, on a third child in a sled. The first child exerts a force of 78 N. the second a force of 9/ N, kinetic friction is 6.5 N, and the mass of the third child plus sled is 235 kg. Using a coordinate system where the second child is pushing in the positive direction, calculate the acceleration in m/s.
