Please answer 1 and 2!

1. A gear rotates at an angular speed of 0.06 rad/s; its speed is then increased to 2.2 rad/s at an angular acceleration of 0.70 rad/s2 . Find the angle through which the gear rotates before reaching this final speed. 2. A tire placed on a balancing machine in a service station starts from rest and turns through 4.7 revolutions in 1.20 s before reaching its final angular speed. Calculate its angular acceleration assuming uniform motion
