Problem $15\mathrm{.}049-$ A planetary gear system

In the planetary gear system shown, the radius of gears $A,B,C,$ and $D$ is $30$ mm and the radius of the outer gear EIs $90$ mm $.$ Know that gear Ehas an angular velocity of $210$ rpm clockwise and that the central gear A has an angular velocity of $270$ rpm clockwise.

Problem $15\mathrm{.}049.$a $-$ Angular velocity of the planetary gear

Determine the angular velocity of each planetary gear.

The angular velocity of each planetary gear is $[*$ ripm $($clockwise$)$
