Note that the direction of the friction force, f = 5.9 N, is unspecified; it will be opposite in direction to the sum of the other two forces. 30 Free-body diagram theexpertta.com 50% Part (a) Find the magnitude, in meters per squared second, of the acceleration of the 49 kg sled and child system. a = 0.0326 Correct! 50% Part (b) Let east be towards the right of the sketch, and let north be towards the top of the sketch. Assuming the sled starts at rest, find the direction of the velocity in degrees north of east. Grade Summary
