The position (in centimeters) of an object oscillating up and down at the end of a spring is given by s equals Upper A sine left parenthesis StartRoot StartFraction k Over m EndFraction EndRoot t right parenthesis
at time t (in seconds). The value of A is the amplitude of the motion, k is a measure of the stiffness of the spring, and m is the mass of the object. What is the greatest acceleration obtained by the object?
A.
StartFraction Ak Over m EndFraction
cm/sec squared

Over the course of the school year, you keep track of how much snow falls on a given day and whether it was a snow day. your data indicates that of twenty-one days with less than three inches of snow, five were snow days, while of the eight days with more than three inches of snow, six were snow days. if all you know about a day is that it is snowing, what is the probability that it will be a snow day?
