    vf =0
    vo = 5m/s
    a=g.sin(theta)
    theta=20 degree
    g=-9.8 m/s^2
    s=?
    use

    s= [vf^2 - vo^2]/2a

    Ans=1.4 m

  2. Hey there, I did the same question but I got 3.78m as my final answer. I used the same calculation and values that you did too.

  4. The solution is correct but he/she used radians instead of degrees

  5. If you got 3.78, chances are you dropped the 2 in the denominator. 2a, not just a. 1.4 is correct.
