question

A bar pivoting about one end has an angular velocity of 8 rad/sec clockwise when it is subjected to a constant angular deceleration, which is to act for a time interval until the bar has an angular displacement of 10radcounterclockwise from its position at the instant at which the deceleration was first applied. The bar will have moved through a total angular distance of 26radin this same time interval. What will be the angular velocity at the end of the time interval?
