    Integrating Force: Derive Distance L for AP Question

    jdavel: i don't know how to derive... Doc Al: Would it be change in F dt= change in MV, F= MV-M0/t=MV/t? t=2L/3V, F= 3MV^2/2L

    Integrating Force: Derive Distance L for AP Question

    This last part of an AP questions is giving me some trouble, mostly because i involves integrating and i never took Calculus. Part D: The dart is now shot into a block of wood that is in a fixed place. The block exerts a Force F on the dart that is proportional to the dart's Velocity V and in...

    Solving AP Physics Problem - Find Total Impulse on 5kg Ball

    o wait, wouldn't it be 4000=(.5x26)-(.5v), V=7974... that defiantly isn't right

    Solving AP Physics Problem - Find Total Impulse on 5kg Ball

    so i did J=2000(6-4), J=4,000.. so basically area under the FxT graph is the impulse... sasme as area in VxT=distance... next part is to find the horizontal velocity of the ball, which so if i know mv of block, i can use J=change in momentum... so 4000=(26x.5)-(5xV). so Velocity= hm... nevermind...

    Solving AP Physics Problem - Find Total Impulse on 5kg Ball

    i know impulse=change in potentional, or the intengral of dt? i haven't taken calculas yet so i have no idea about derivatives and integrations

    Solving AP Physics Problem - Find Total Impulse on 5kg Ball

    Hey I am in 12 grade but this is advanced placement so its college level... Anyways i could use some help on this problem i have A 5kg ball initally rest at the edfe of a 2-meter long, 1.2 meter high frictionless tavle, as show above. A hard plastic cude of mass .5kg slides across the table...
