Upon impact, bicycle helmets compress, thus lowering the potentially dangerous acceleration experienced by the head. a new kind of helmet uses an airbag that deploys from a pouch worn around the rider’s neck. in tests, a headform wearing the inflated airbag is dropped onto a rigid platform; the speed just before impact is 6.0 m/s. upon impact, the bag compresses its full 12.0 cm thickness, slowing the headform to rest. what is the acceleration, in g’s, experienced by the headform?

Awind turbine is initially spinning at a constant angular speed. as the wind's strength gradually increases, the turbine experiences a constant angular acceleration 0.173 rad/s2. after making 2870 revolutions, its angular speed is 132 rad/s. (a) what is the initial angular velocity of the turbine? (b) how much time elapses while the turbine is speeding up?
