Question

The toy gun in the figure below consists of a spring with spring constant k. Itis loaded with a projectile of mass mand the spring is compressed a distance d. The toy gun is fired horizontally and the bullet travels a total distance Lwithin the toy gunbefore it is released. A) Neglecting all resistive forces, determine the speed of the projectile v0once it exits the toy gun(i.e., expressv0 in terms of the known quantities k, m, L, d).B) Suppose now that there is an average friction force of magnitude fthat acts on the projectile as it travels through the toy gun. If the final velocity of the projectile is v1, calculate f (i.e., find an expression for fin terms of k, m, L, d, and v1).
