A Red Rider bb gun uses the energy in a compressed spring to provide the kinetic energy for propelling a small pellet of mass 0.26 grams. By cocking the lever attached to the stock of the rifle, the spring (k = 2000 N/m) is compressed 9.5 cm from its equilibrium point. What is the potential energy energy stored in the compressed spring? A: 3.6966 B: 4.6208 C: 5.7760 D: 7.2200 E: 9.0250 J

What is the kinetic energy of the pellet when the spring is released? A: 3.6966 B: 4.6208 C: 5.7760 D: 7.2200 E: 9.0250 J

What is the muzzle velocity of the bb? A: 198.1072 B: 263.4826 C: 350.4318 D: 466.0744 E: 619.8789 m/s

If the rifle was modified so that the spring could be compressed twice as far, 19 cm, what would be the resultant muzzle velocity of the bb? A: 384.9552 B: 450.3976 C: 526.9652 D: 616.5493 E: 721.3626

    A spring gun is made by compressing a spring in a tube and then latching the spring at the compressed position. A 4.97-g pellet is placed against the compressed and latched spring. The spring latches at a compression of 4.07 cm, and it takes a force of 9.12 N to compress the spring to that point. (a) If the gun is fired vertically, how fast is the pellet moving when it loses contact with the spring? (Include the effect of...

  • A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air

    A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...

    For the sake of directional stability, the bullet fired from a rifle is given a spin angular velocity about its axis by means of spiral grooves ("rifling") cut into barrel. The bullet fired by a Lee-Enfield rifle is (approximately) a uniform cylinder of length equal to 3.18 cm, diameter equal to 0.790 cm, and mass equal to 13.9 g. The bullet emerges from the muzzle with a translational velocity of 622 m/s and a spin angular velocity of 2.78 103...
