Ablock of mass m is pressed against an ideal spring of constant k, compressing the spring by an amount d. the block is released, and slides on a frictionless surface. when it reaches the equilibrium length of the spring, it leaves the spring and continues to slide until it collides elastically with a statonary block of mass m2 = m/3. find each of the following. your answers should be expressed in terms of k, m, and d. a) the velocity of the large block when it leaves the spring b) the velocity of the large block after the collision c) the velocity of the small block after the collision
