Question

REMARKS The normal force ni, the gravitational force mš, and the upward component of the applied force do no work on the sled because theyre perpendicular to the displacement. The mass of the sled didnt come into play here, but it is important when the effects of friction must be calculated and in the work-energy theorem. QUESTION How does the answer for the work done by the applied force change if the load is doubled? 0 The work is doubled. 0 The work is halved. 0 The work is the same. Explain Do not forget to explain it

    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....
