Calculating velocity on an inclined plane

  1. Jul 12, 2011 #1
    So, this particular plane is angled so that a certain object will roll at a constant acceleration of 2 m/s each second. The object's initial velocity will be zero and in one second its velocity will be 2 m/s, but will only have traveled 1 m during that duration between zero and one seconds. Is this true because the object does not travel, initially, 2 m/s?

    well aceleration is m/s^2 not m/s and you should use the 5 kinematic or constant acceleration equations
    ie v2^2 = v1^2 +2aD
    2^2 = 0 + 2(2)(D)
    D=1
    So the certain object will reach a speed of 2m/s with a accelertaion of 2m/s^2 in 1 meter.
    And yes it is because the object is initially at rest

    velocity ≠ acceleration. For constant uniform acceleration a in one dimension, with zero initial velocity, the displacement s is:

    s = at2/2
