A light pole of height 15 meter has a lamp hanging at its top . from a distance 12 meter from the base of the pole , a ball is thrown vertically upwards with velocity 5m/sec . find the rate at which the shadow of the ball on the earth moves away from the base of the pole after 0.5 second.
I'll try and figure it out in just a minute. Let me work it out before I answer your question. You can ask it again as a reminder for me.
Thanks,
