Your glass half full travels across the table at initial speed vi = 2.6 m/sec. Glass and water together add up to a mass of m = 0.22 kg. The underside is wet, so kind of slippery, with frictional force f = 0.29 N retarding the motion.

Question

Your glass half full travels across the table at initial speed vi = 2.6 m/sec.  Glass and water together add up to a mass of m = 0.22 kg.  The underside is wet, so kind of slippery, with frictional force f = 0.29 N retarding the motion.
