0 to 180

Bob's wife got a little suspicious because he had come home late from work a lot recently. So she told him that by Friday, he better spend some money and she better see something that goes from 0 to 180 in 6.5 seconds. Bob got the hint and on Friday morning, woke up his wife and said "Honey, come on outside and see what I got you." The wife went down the stairs and to her surprise saw nothing in the driveway but then noticed she had stepped on a scale and she watched as it spun up from 0 to 180. Bob was not seen at work the next Monday.
