1 A wheel is rotating and is slowing down with constant angular deceleration. The initial angular speed is \(80 \mathrm { rad } \mathrm { s } ^ { - 1 }\), and after 15 s the wheel has turned through 1020 radians.
- Find the angular deceleration of the wheel.
- Find the angle through which the wheel turns in the last 5 s before it comes to rest.
- Find the total number of revolutions made by the wheel from the start until it comes to rest.
