The barricade at the end of a subway line has a large spring designed to compress 2.00 m when stopping a 1.45 ✕ 105 kg train moving at 0.590 m/s.

(a) What is the force constant of the spring?
N/m

(b) What speed would the train be going if it only compressed the spring 0.760 m?
m/s

(c) What force does the spring exert when compressed 0.760 m? (Enter the magnitude only.)
N
