50. A glider with mass m = 0.200 kg sits on a frictionless, horizontal air track, connected to a spring with force constant k = 5.00 N/m. You pull on the glider, stretching the spring 0.100 m, and release it from rest. The glider moves back toward its equilibrium position (x = 0). What is its x-velocity when x = 0.080 m? ans - 0.30 m/s
A spring gun (k = 28.0 N/m) is used to shoot a 41.3-g ball horizontally. Initially the spring is compressed by 18.0 cm. The ball loses contact with the spring and leaves the gun when the spring is still compressed by 12.0 cm. What is the speed of the ball when it hits the ground, 2.66 m below the spring gun? m/s

デジタル形式で段階的に解決ありがとう!! SOLVE STEP BY STEP IN DIGITAL FORMAT A toy gun uses a spring for which k = 20 N/cm. When loaded, the spring compresses 3.0 cm. How high will a 5.0 g projectile fired from this gun reach? Ans. 18 m.
A 50 g ice cube can slide without friction up and down a 30º slope. The ice cube is pressed against a spring at the bottom of the slope, compressing the spring 13.0 cm. The spring constant is 25 N/m. When the ice cube is released, what distance (in cm) will it travel up the slope above the release point before reversing direction? Use g = 10 N/kg. In your calculations, make sure you convert to consistent units (kg and meters).
