A small ball with a mass of 60.0 g is loaded into a spring gun, compressing the spring by 12.0 cm. When the trigger is pressed the ball emerges horizontally from the barrel ata height of 1.40 m above the floor. It then strikes the floor after traveling a horizontal distance of2.20 m. Use g = 9.80 m/s2.Assuming all the energy stored in the spring is transferred to the ball, determine the spring constant of the spring.
