The wheel of fortune is 2.6 meters in diameter. a contestant gives the wheel an initial velocity of 2 m/s. after rotating 540 degrees, the wheel comes to a stop. calculate the angular acceleration of the wheel. show your work.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
