A metal sphere with a mass of 0.020 kg rolls along a friction-less surface at 3.2 m/s and strikes a stationary sphere having a mass of 0.041 kg. The first sphere stops completely. The spheres are in contact for 0.005 s before the second sphere is shot off down the track. What is the force applied to the second ball?
