10x-16 Bikes and Buses

  • 0:00 - 0:05
    When travelling in a city, it can often be faster to use a bicycle than to take a bus.
  • 0:05 - 0:09
    One reason for this is that bikes are able to accelerate faster than buses can.
  • 0:09 - 0:12
    Now, let's say that a bike and a bus both stopped at a red light,
  • 0:12 - 0:15
    take off at the exact same time when the light turns green.
  • 0:15 - 0:22
    The bike can accelerate at 1.2 m/s² but only to a top speed of 12 m/s.
  • 0:22 - 0:28
    The bus on the other hand can accelerate at 0.8 m/s² to a top speed of 20 m/s.
  • 0:28 - 0:31
    Now, since the bike has a higher initial acceleration,
  • 0:31 - 0:34
    it will be in front of the bus for some time.
  • 0:34 -
    I want to know how much time elapses before the bus catches up with the biker.
