(a) What is the algebraic expression for the speed of the fastest train that could be stopped by the spring in terms of the maximum compression of the spring (L), the weight of the train (W), and the gravitational acceleration (g)? [Note: Don't enter an equation like "x=blah". Just enter the "blah" part. All letters are capital except for "g".]

(b) What is the numerical value of the speed of the fastest train that could be stopped by the spring (make sure to include units and put a space between the number and the units)?
