Two pucks, each of mass m, are connected by a massless string of length 2l as illustrated below. the pucks lie on a horizontal, frictionless sheet of ice. the string is initially straight (i. e., θ = 90o ). a constant, horizontal force f is applied to the middle of the string in a direction perpendicular to the line joining the pucks. when the pucks collide, they stick together. how much mechanical energy is lost in the collision?

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
