Which one has the greater deceleration

  1. Oct 22, 2012 #1
    I'm just wandering. Because I have a debate with my classmate.
    Which one has the greater deceleration a bicycle with an acceleration of 0.5 meters per second or a car with 0.83 meters per second.
    I think the answer is the bicycle. :)
    Please give me your opinion or nearly the real answer. Thank You.

    Why do you think it is the bicycle?
    And what are the units of acceleration?

    Base on the findings, the bicycle has the smaller acceleration than the car has. And the question is which has the greater deceleration.
    The units are meters per second.

    I already stated this in my post above. :3

    Meters per second is the unit of velocity, not acceleration. You'll have to state the problem more precisely before we can answer.

    Aw. I'm very sorry. It's meters per second square rather. :D

    Insufficient information to even make a guess. Do some measurements and figure it out.
