A mass sitting on a horizontal, frictional surface is attached toone end of a string, the other end of a wall. 6.0 J of work isrequired to compress the spring 0.14 m. If the mass is releasedfrom rest with the spring compressed, it experiences a maximumacceleration of 13 m/s2
a) Find the value of the spring constant
b) Find the value of the mass
