A fire truck supplies 5 bars of water pressure (gauge). Neglect viscous effects (pressure losses) and air resistance effects for the purpose of estimation. Assume the elevation of the fire truck is 0 m. (a) how high can water be shot upward?.

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
