Physics -> Circular Motion & vector problem?

How can you count the maximum angular velocity if you only know the radius, the angular velocity when when t = o, the degrees when t = 0 and the angular acceleration as a function of t? (a = xt + y)

    There is no maximum. Angular velocity will keep getting bigger as time goes on.

    Angular anceleration a = dα/dt where α is angular velocity

    a = xt + y

    dα/dt = xt + y

    Integrate:

    α = 2xt² + yt + C where C is a constant.

    By using the known value of α when t=0, you can calculate C.

    a million) only the momentum may be shared by technique of two products of equivalent mass, simply by fact the area each merchandise is from the midsection of their respective planets, by technique of the regulation of gravity, might supply a distinctive acceleration of gravity for each planet. Mass is self sustaining of gravity and for this reason does not result momentum (that's =to mass x velocity). So, B is the respond. 2) Is C. From a(c)=v^2/r v=(a(c)r)^0.5 =(3.0m/s/s x 300m)^0.5 =30m additionally it would desire to be shifting clockwise simply by fact centripetal acceleration constantly is directed to the midsection of the circle of an arc. The eastward velocity places the vehicle on the suited of the "circle" which then might have the acceleration vector pointing in to the circle, south. 3) From d=vt+0.5at^2 =24m/s(11s)+ 0.5(-6m/s/s)(11s)^2 =-99m So i assume which would be E. (You look to have 2 99m alternatives)
