Question 6. A spring-loaded toy gun is used to shoot a ball of mass m = 0.015 kg straight up in the air. The spring has spring constant k = 250 N/m. The initial situation is A, shown, in which the spring is compressed by an amount hminl = 0.025 m. The ball is released from rest at point A, and is pushed up to point B by the spring. At point B the spring is in equilibrium, and we define the ball to be at height y = 0. What is the maximum height at point C, hmax, to which the ball reaches before it stops? --C:y=+hmax -B: y=0 A: y=-hmin O 0.51 m 0.89 m O 1.1 m O 1.3 m 1.6 m
