[This is a particularly challenging problem, incorporating momentum, conservation of energy, and centripetal force. If you find yourself getting annoyed, just remember that I could have turned the block into a projectile as well :-). Consider it a bonus.] A bullet of mass m = 40 g, moving horizontally with speed v, strikes a clay block of mass M = 1.68 kg that is hanging on a light inextensible string of length L = 0.620. The bullet becomes embedded in...

Using a thin lens with a focal length of f = +5.2cm, a student makes two measurements. She finds the distance to the object to be o = +3.1cm. What distance, i, should she expect for the image? Explain whether this is a real or virtual image using the sign convention. Then find the magnification of the image also explaining your answer using the sign convention.
