挑戰一:某連隊等速直線前進,部隊全長 600m,傳令兵自隊尾等速跑到隊首遞交報告給連長後, 立刻以原速率跑回隊尾,此時整個連隊恰好前進了800m,則全程傳令兵移動的路徑長為?/boom # A popular web video shows a jet airplane, a car, and a motorcycle racing from rest along a runway. Initially the motorcycle takes the lead, but then the jet takes the lead, and finally the car blows past the motorcycle. Here let's focus on the car and motorcycle and assign some reasonable values to the motion. The motorcycle first takes the lead because its (constant) acceleration am 8.40 m/s² is greater than the car's (constant) acceleration ac 5.60 m/s², but it soon loses to the car because it reaches its greatest 58.8 m/s before the car reaches its greatest speed 106 m/s. How long does speed the car take to reach the motorcycle? 16.6

And they may need to wear heavier beekeeping suits even in hot, 14. weather. Beekeepers may also collect less honey from Africanized bee hives. European bees form search parties and work together to collect flower nectar from which honey is made, while Africanized bees usually work alone in search of flowers. Therefore, less nectar is brought back to Africanized bee hives. Africanized bees also spend less time storing honey but more time caring for young bees.
