An object moving along a horizontal track collides with and compresses a light spring (which obeys Hooke's Law) located at the end of the track. The spring constant is 51.4 N/m, the mass of the object 0.280 kg and the speed of the object is 1.60 m/s immediately before the collision. (a) Determine the spring's maximum compression (in m) if the track is frictionless. m (b) If the track is not frictionless, will the spring's maximum compression be greater than, less than, or equal to the value obtained in part (a)
