Compute all parts of given question:

Question: You are pulling your friend in a sled in a straight line to the right at a constant speed. The mass of your friend plus the sled is 70 kg. The coefficient of kinetic friction is 0.15. You exert a force of 150N on the string attached to the sled at an angle of 35 degrees above the horizontal.

Part I: Draw a force diagram of the system including all forces on the sled. Use the method for labeling forces used in class with the two subscripts and identify what the subscripts mean.

Part II: Set up your sums of forces in the x and y directions.

Part III: Calculate the acceleration of the sled/ person.

Part IV: How long would it take to move the sled/person from rest to 3 m/s ?

Part V: How far would the sled/ person travel in this time?

Please show all work and steps to find the acceleration of the sled/ person.
