The electric potential in a certain region is given by the equation v ? 30x21,3-2)x214.2 where the potential is in volts when the positions are given in meters. the constants in this equation are ? -3.2 vm5 and y-0.18 vm8 25% part (a) write an equation for the x-component of the electric field

The 5-kg cylinder is initially at rest when it is placed in contact with the wall b and the rotor at a. if the rotor always maintains a constant clockwise angular velocity v = 6 rad> s, determine the initial angular acceleration of the cylinder. the coefficient of kinetic friction at the contacting surfaces b and c is mk = 0.2.
