010 (part 1 of 2) 10.0 points A crate is lifted vertically 1.5 m and then held at rest. The crate has weight 100 N (i.e., it is supported by an upward force of 100 N). How much work was done in lifting the crate from the ground to its final position? 1. No work was done. 2. None of these 3. More than 150 J 4. A bit less than 150 J 5. 150 J 011 (part 2 of...

A 1500-kg air conditioning unit is being lifted by a crane onto the roof of a building. The unit starts on the ground and is raised straight up to a height of 12.0 m by a cable attached to the crane. The tension in the cable during the lift is 1.54 × 104 N. (Reminders: a free body diagram will probably be helpful, and work can be positive or negative.) (a) How much work is done on the air conditioning...
