O PowerPoint Slide Show - [WORK_E~3 [Compatibility Mode]] - PowerPoint Spring / projectile problem After Moe hits Curly on the head with a hammer Curly retaliates by firing a dart at him with a suction cup tip from spring-loaded dart gun. The dart's mass is 15 g and the spring constant of the spring in the 22 N/cm. When loaded, the spring is compressed 3 cm. Curly fires the gun at an angle of 19° below the horizontal from up on a ladder. He misses Moe, but the dart hits Larry and sticks to his forehead 1.4 m below. What is the range of Curly's dart? gun is Hints on next slide.
