A99.5 n grocery cart is pushed 12.9 m along an aisle by a shopper who exerts a constant horizontal force of 34.6 n. the acceleration of gravity is 9.81 m/s 2 . if all frictional forces are neglected and the cart starts from rest, what is the grocery cart’s final speed? answer in units of m/s. 003 (part 1 of 4) 10.0 points in the 1950’s, an experimental train that had a mass of 36300 kg was powered across a level track by a jet engine that produced a thrust of 4.28 × 105 n for a distance of 586 m. find the work done on the train. answer in units of j. 004 (part 2 of 4) 10.0 points find the change in kinetic energy. answer in units of j. 005 (part 3 of 4) 10.0 points find the final kinetic energy of the train if it started from rest. answer in units of j. 006 (part 4 of 4) 10.0 points find the final speed of the train assuming no friction. answer in units of m/s.
