Suppose the ski patrol lowers a rescue sled and victim, having a total mass of 80.0 kg, down a

θ = 70.0°

slope at constant speed, as shown in the figure.

coefficient of friction between the sled and the snow is 0.100.

(a) How much work is done (in J) by friction as the sled moves 30.0 m along the hill? -805.25 J

(b) How much work is done (in J) by the rope on the sled in this distance?

(c) What is the work done (in J) by gravity on the sled? J (d) What is the total work done (in J)? J

I got A right! I just need B and C

Your question is interesting, but you missed mass of the sledge. But don't worry. I calculated mass by ur answer provided for part a.

Plz thumb if you feel better. Thanks for using HomeworkLib.

    Suppose the tractor pulls horizontally on the sled instead of at an angle of 36.9. As a result, the magnitude of the friction force increases to 4400N. What is the total work done on the sled? Answer: 1.20x10 J onedo 72 Work 187 SOLUTION The statement of the problem gives the hright h rather than the distance s measured along the ramp, but we can solve for h by recogsizing from the geometry in Figare 7.13 that s sinB- h....
