    Finding the velocity of an object being pushed up an angular slope

    ok so I have W_g=-9.8 my W_c=22 and my W_friction=-8.487, so then I add those sums to get my total work done which is W=3.713 then I plug that into the Kinetic energy theorem and have the v=sqrt(2*W/m)...sqrt(2*3.713/1)=2.72...and the answer is 3.2[M/s]...am I still making errors?

    Finding the velocity of an object being pushed up an angular slope

    Oh yea... I have been poking in numbers for a while i did the angle of that to be zero as well so then my work done for the constant is W_c=11*2*cos(0degrees).. or am I still wrong... haha..which is 22

    Finding the velocity of an object being pushed up an angular slope

    Would it not just be the angle of 30 degrees which the slope is angled at?

    Finding the velocity of an object being pushed up an angular slope

    [b]1. A box mass m=1 kg is pushed up an incline of an angle theta=30 degrees that has a coefficient of kinetic friction u_k=.5. Find the velocity of the object after it pushed for d=2m by a force of magnitude F=11N directed upward alone the incline. W_g=m*g*d*cos(90+theta) W_constant...
