A sled of mass 49.0 kg is pulled along flat, snow-covered ground. The static friction coefficient is 0.30, and the kinetic friction coefficient is 0.10. 1. How much force will be needed to start the sled moving? N II. How much force is needed to keep the sled moving at a constant velocity? N III. Once moving, how much force must be applied to the sled to accelerate it at 3.3 m/s2? N For all responses, give three sig figs. (NOT three decimal values)​
