Apeople-moving conveyor-belt moves a 600-newton person a distance of 100 meters through the airport.
a. how much work was done?
b. the same 600-newton person lifts his 100-newton carry-on bag upward a distance of 1 meter. they
travel another 10 meters by riding on the “people mover.” how much work was done in this situation?

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
