    You're the only teacher that makes engineering classes fun. Thank you for all the videos!

      I know I'm 6 years late but I have to say he makes it so understandable and easy to follow, and my first Language isn't even English haha

    I'm in Dynamics right now, it sucks this is your second to last video but I appreciate all of the hard work Dr. Hanson! You got me through solids and statics.

    Couldn't Find any better mechanics professor than You! I got a good grade on statics (thanks to your lessons) And I hope You complete recording rest of dynamics lessons by the end of the semester.
    By all means, Thank You.

    I am so grateful for all your hardwork Dr. Hanson, I wish professors in my university put in half as much effort in teaching! You have helped many many students like me! Thank you.

    Thank you very much, Dr. Hanson! You' saved me in Statics, you'll save me in Dynamics

    Professor Hanson, thank you for a classic selection and analysis of Projection Motion in Mechanics Two. This problem is well known in Physics.

    Does your calculator use voice recognition cause how did you input those quadratic figures lol

    when breaking down velocity into x and y components, shouldnt there be cos and sin there?

    • @malakihmeidan9839
      @malakihmeidan9839 11 หลายเดือนก่อน

      since there was no angle given you cant do it with sin and cos, the other way to do it is with similar triangles (how he did it). If there was a theta given you would use sin and cos

    Why didn’t we use Vy=V0+act where final velocity in Y direction is zero and we solve for time

    What textbook do you use sir?
    Or would you recommend?

    • @dawooddawood3158
      @dawooddawood3158 2 ปีที่แล้ว +1

      I think he uses R.C Hibbler's Engineering Mechanics Dynamics

    DR. at 5:35 i think [ VY=vsin 3/5 -gt ] not VY=VSIN3/5 ANY WAY THANKS { and my final answers are T=18.06sec D=2167.2 metre

    what about solid class? its been a month :(

  • @johnnyc2473
    @johnnyc2473 6 ปีที่แล้ว

    What if your not given the angle. Your only given the height of the building, the horizontal acceleration, and gravity?

  • @lukedimitriades9835

    “Because gravity sucks, right”😂😂

      it really "sucks", pun intended =)

  • @Aviationinmymind
    @Aviationinmymind 4 ปีที่แล้ว

    Isn't air resistance also causing acceleration on the projectile? It has X and Y components.

    Why is gravity negative

    Why is the accerelation negative

    • @Jeff-xy7fv
      @Jeff-xy7fv 3 ปีที่แล้ว

      Because gravity pulls down; not up.

  • @jeremychee173
    @jeremychee173 2 ปีที่แล้ว

    The last problem I believe you forgot the second term of the distance equation (1/2*at^2). The answer should be 448.57m the value in the video is almost a mile and a half.

    • @moreywilkerson8378
      @moreywilkerson8378 ปีที่แล้ว

      you sent this a while ago, but because wind is ignored the Vertical accelleration is zero.

  • @katyar4883

    The thing is, I understand this example so easily but the homework is not like this.

      Hi Jeff hey I'm confused why do you plot 150 as the initial position to find t and why you didn't to find the final position instead you use zero? 🤔
