There is a clever kitchen gadget for drying lettuce leaves afteryou wash them. it consists of a cylindrical container mounted sothat it can be rotated about its axis by turning a hand crank. theouter wall of the cylinder is perforated with small holes. you putthe wet leaves in the container and turn the crank to spin off thewater. the radius of the container is 12 cm. when the cylinder isrotating at 2 revolutions per second, what is the magnitude of thecentripetal acceleration at the outer wall?
a. 4.8 m/s2
b. 19 m/s2
c. 27 m/s2
d. 9.8 m/s2
e. 6.0 m/s2

An insurance company wants to know if the average speed at which men drive cars is higher than that of women drivers. the company took a random sample of 27 cars driven by men on a highway and found the mean speed to be 72 miles per hour with a standard deviation of 2.2 miles per hour. another sample of 18 cars driven by women on the same highway gave a mean speed of 68 miles per hour with a standard deviation of 2.5 miles per hour. assume that the speeds at which all men and all women drive cars on this highway are both approximately normally distributed with unknown and unequal population standard deviations.
