1) The trap-jaw ant can snap its mandibles shut in as little as 1.2×10-4 s. In order to shut, both mandibles rotate through a 94° angle. What is the average angular velocity of one of the mandibles of the trap-jaw ant when the mandibles snap shut?

2) A jet is circling an airport control tower at a distance of 18.0 km. An observer in the tower watches the jet cross in front of the moon. As seen from the tower, the moon subtends an angle of 8.96×10-3 radians. Find the distance traveled (in meters) by the jet as the observer watches the nose of the jet cross from one side of the moon to the other.

3) A gymnast is performing a floor routine. In a tumbling run she spins through the air, increasing her angular velocity from 3.20 to 4.50 rev/s while rotating through one half of a revolution. How much time does this maneuver take?

Can anyone please help me please!! Please!!
Thank you in advance!!
