- F(x) A 8kg block initially at rest is acted on by the force shown at an angle of 0 = 20'. The magnitude of this force changes as the block 4. moves: F(x) = (7.5 N/m)x. The coefficient of kinetic friction between the floor and the box is µ = 0.2. Determine the speed of the block after the block has moved 5.0m.Question 10 A 10.0 kg child on a 5.0 kg sled, starting from rest, goes down a frictionless hill with a height of 3.25 m. As soon as it reaches the bottom of the hill the sled hits a gravel patch on level ground with a coefficient of friction of 0.72. How far does the sled travel before coming to a stop?
