A small source of light Sis located at a distance Lfrom a vertical wall. An opaque object with a height of h moves toward the wall with constant velocityv_vec of magnitude v. At time t= 0 , the object is located at the source S. Find an expression for v_s, the magnitude of the velocity v_s_vec of the top of the object's shadow, at time t.
Express the speed of the top of theobject's shadow in terms of t, v,L, and h.
