    Sledge sliding down hill and across flat area with friction

    Oh! Didnt see that!i Will try to see if i get something else. Thank you EDIT: Solved! Cant believe i used to hours to figure out a stupid mistake like that haha. Thank you a lot!

    Sledge sliding down hill and across flat area with friction

    isnt 1.85*6 Isnt 1.85*(6/12.5)=0.888? 1.85*(0.48)=0.888?

    Sledge sliding down hill and across flat area with friction

    Known h0=3.0m d1=6.0 m (From top of the hill diagonaly down to the flat area) d2= 12.5 m (Flat area) Ep=0J (Since no potenial energy at the end of the ride) Ek0=0j (Since no movement at the top of the hill) Friction on d1 is 85% of the friction power to d2 Unknown V(Velocity)

    Sledge sliding down hill and across flat area with friction

    I posted some of my calculations above which might be completely wrong. However i will try to do make some more calulculatiions i can post.

    Sledge sliding down hill and across flat area with friction

    Here is some of my calulations, warning: this might be completely wrong. EDIT: s=distance. S is distance in my language :)

    Sledge sliding down hill and across flat area with friction

    The flat portion is 12.5m. 6.5m is from the diagonal line from the top of the hill to the flat area. Sorry for late answer, just took bus from library to home. Maybe this drawing can clear some things up.
