Problem 43 (Plug-n-chug). A spring cannon shoots a ball with a mass of 9.6 g vertically into the air from ground level. In this situation, air resistance can be ignored. The spring is compressed by a distance of 3.4 cm below the mouth of the cannon. If the ball reaches a maximum height of 96 cm above the mouth of the cannon, then what is the spring constant of the spring in the cannon? Round your answer to the nearest 10 N/m. (а) 140 N/m (b) 150 N/m (c) 160 N/m (d) 170 N/m (e) None of these
