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

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
