1.If a unit mass of groundwater accelerates from rest to an average linear velocity of 1 m per year and climbs a vertical distance of 1 m, compare the ratio of kinetic energy to the potential energy of the unit of groundwater. Is it reasonable for us to ignore the kinetic energy associated with groundwater movement?

2.From a videotape, it was observed that a player kicked a football 126 {\rm ft} during a measured time of 3 seconds. Determine the initial speed of the ball and the angle(theta) at which it was kicked
