two independent wheels start from rest and are given the same angular acceleration. the first wheel turns through (theta) radians before it reaches an angular velocity of (w) How many radians does the second wheel turn through before it reaches an agular speed of 13 (w)?

The weights of bags filled by a machine are normally distributed with a standard deviation of 0.05 kilograms and a mean that can be set by the operator. at what level should the mean weight be set if it required that only 1% of the bags weigh less than 9.5 kilograms? round the answer to 2 decimal places.
