    How Long Does It Take a Block to Slide Down a Frictional Incline?

    I was able to get friction because fn = f perpendicular. So i did .10 x 96 and got friction to equal -9.6

    What do you mean? Didn't i just solve for parallel and perpendicular force?

    correct, fx = sin10mg = sin10 x 10 x 9.8 = 17 fy = cos10mg = cos10 x 10 x 9.8 = 96

    Ok i did that, I just don't know what to solve for first.

    How Do You Calculate Resultant Velocity in Vector Addition?

    So my total for x was 111 and for y it was 213. So then I used pythagorean theorem and got 240. I'm not sure if this is correct though. And then for my angle i got 62.5

    How Do You Calculate Resultant Velocity in Vector Addition?

    You use sinΘ or cosΘ, and then you times that number by the velocity.

    How Do You Calculate Resultant Velocity in Vector Addition?

    Homework Statement A plane heads 20° north of east at 200 m/s. The wind blows 60° north of east at 50 m/s. What is the resultant velocity of the plane? Homework Equations Δv= v2-v1 or Δv= v2+(-v1) The Attempt at a Solution I know you have to solve for the x and y, but I don't know...
