1.A wheel rotates with constant angular acceleration, starting from rest.After 6.00 s it has rotated 25.0 radians.(a) What is the angular acceleration of the wheel?(b) What is the angular speed of the wheel after 6.00 s?(c) What is the centripetal acceleration of a bug stuck on the wheel a distance of 45.0 cm from the axis of rotation?

2.A ball is tossed straight upwards with a spinning motion.The ball turns 7.20 revolutions (q) at a constant rate of 31.0 rad/s (w) when it returns to the person's hand.How high did the ball go?As a challenge (but reluctantly not required), derive a symbolic expression first.

3.A car engine idles at 800. rpm in neutral.While in neutral you "rev the engine" by stepping on the accelerator (I guess you like wasting gas and contributing to the heat death of the universe.)The tachometer reads 3400. rpm after 1.20 s.(a) What is the average angular acceleration during this time interval?Answer in rad/s².(b)How many revolutions does the engine turn in this time interval?
