Chapter 1: Q. 60 (page 31)

Write a short description of a real object for which Figure p1.60 would be a realistic position-versus-time graph.

Short Answer

Expert verified

A crane operator checks his load of a ton of bricks for 4 seconds while it is 30 m off the ground, then begins to lower it at a constant speed. He lowers it 15 m in 4 seconds. Then he stops for 4 seconds to make a second safety check. he then continues lowering the bricks the remaining 15 m in 8 seconds until they hit the ground.
