You stand 4 meters from the bottom of a lamp post that is 3 m tall. How far would a firefly fly if it flew from your big toe to the lamp?
Height of the lamp post = H = 3 m
Distance of the bottom of the lamp post from you = D = 4 m
Distance the firefly flew from your big toe to the lamp = L
L = 5 m
Distance the firefly flew from your big toe to the lamp = 5 m

A man 5 ft tall is walking away from a lamp post 9 ft tall. If the man is walking at a speed of 4 ft/s, how fast is the length of his shadow changing when he is 61 ft from the lamp post? Rate of change of shadow ft/sec Done
7. (8 points) A 6 foot-tall man is walking away from a lamp post, which is 11 feet tall. Let u represent the man's distance from the lamp post (in feet) and let y represent the length of the man's shadow (in feet), as shown in the picture below. Determine how fast the man is walking if the length of his shadow is increasing at a rate of 12 feet per second.
Nemesis You walk up to a mirror and stand 3.5 meters away How far away from you is your mirror image? reflection distance (m) =
You are 1.9 m tall and stand 2.4 m from a plane mirror that extends vertically upward from the floor. On the floor 1.1 m in front of the mirror is a small table, 0.50 m high. Part A What is the minimum height the mirror must have for you to be able to see the top of the table in the mirror? Express your answer using two significant figures. Please show all work extensively!!
Check my Required information You are standing 1.30 m from a heat lamp that draws an rms current of 15.00 A when connected to 120 Vrms. If you stand in front of the heat lamp for 2.00 min, how much energy is incident on your face? Assume your face has a total area of 2.80 x 10-2 m2
4. Your physics instructor walks towards the front door of Lillard Hall. You stand at the edge of the roof, planning to throw an egg on him (shame on you)! If your instructor walks horizontally at 1.25 m/s towards the door, and you throw the egg upwards at 3 m/s (to make your get-away) at a height of 5 meters above the instructor's head, how far should the instructor be from the door when you start?
Your friend is belching the alphabet. Where you are standing, a distance of 2 meters from your friend, the peak sound level of their belching is 68.2 dB. You would like to move far enough away from them that you won’t have to hear their belching. Assuming that the belch noises approximate spherical waves, how far should you stand from your friend in order for the peak intensity of the sound to be the threshold of hearing, 10^−12 W/m2?
on level ground, you stand 30.0 m from the base of a tree and determine that the treetop is at 42 degrees above the horizontal, as measured from ground level. how tall is the tree?
A guy named Joe, who is 1.6 meters tall, enters a room in which someone has placed a large convex mirror with radius of curvature R equal to 30 meters. The mirror has been cut in half, so that the axis of the mirror is at ground level. (Figure 1) As Joe enters the room, he is 5 meters in front of the mirror, but he is looking the other way, so he fails to see it. When he turns...
