0.7 m 0.4 m B -0.75 m- -0.5 m- The lift truck has a mass of 60 kg and mass center at G. The lift truck lifts a 150 kg spool. The rear wheels in the back freely rotate and front wheels in the front are always slipping. Given that the coefficient of kinetic friction between the wheels and the road is uk = 0.25. Neglect the mass of the wheels. a) Determine the normal reactions on the pair of front wheels and rear wheels if the truck lifts the spool with an acceleration of 5 m/s2. b) After lifting the spool, the truck travels forward with a constant deceleration of 3 m/s2 with speed of 1 m/s. 0.7 m 0.4 m B -0.75 m- -0.5 m- The lift truck has a mass of 60 kg and mass center at G.
