The owner of a van installs a rear-window lens that has a focal length of -0.310 m. When the owner looks out through the lens at an object located directly behind the van, the object appears to be 0.250 m from the back of the van, and appears to be 0.360 m tall. (a) How far from the van is the object actually located, and (b) how tall is the object?

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
