A particle with a velocity of 2m / s at t = 0 moves along a straight line with a constant acceleration of 0.2m / s s.find the displacement of the particle in10 second

asked by ashu
  1. well, every second the velocity increases by 0.2 m/s. So how much is that after 10 seconds?

  3. How did you get 100.2 ??

    a = 2
    v = at+c = 2t + c
    when t = 0, v = 2
    2 = 0 + c

    v = 2t + 2

    s = t^2 + 2t + k
    when t=0 , s = 0 , thus k = 0

    s = t^2 + 2t
    when t = 10
    s = 10^2 + 2(10) = 120

  4. forget about my solution, I saw that as a = 2
    instead of a = .2

    so s = .1 t^2 + 2t
    at t = 10
    s = .1(100) + 2(10) = 30 m
