A man walking with spped ‘v’ constant in magnitude and direction passes under a lantern hanging at a height H above the ground (consider lantern as apoint source).Find the velocity with which the edge of the shadow of man’s head moves over the ground?

Question

Vikas TU · Answer

U would have to draw the situation first then similarize thriangles to get the relation in height and speed. . Assume at s distance the lamp is at h height and H remained as and s0 be the shadow distance with s0 > s. then similar the triangles U would get as: v/(H-h) = v’/H get the v’.
