Homework Statement
One man, with height h, is inside a room. On the ceiling of the room there is a candle that is at a height H from the floor. The man moves in a straight line with velocity v1, passing below the candle.
a) Determine the velocity of the shadow of his head projected on the floor.
b) What is the relationship between the velocity of the man and the velocity of the shadow of his head when he walks outside below the sun.
Homework Equations
The Attempt at a Solution
a)
[tex]v_{\rm shadow}=\left \frac{H}{H-h} \right v_1[/tex]
b)
In this case, H >> h, so vshadow=vman.
Am I right? Thanks in advance for your replies.
