This is a very easy question. Setting the problem up is not a problem. However, the units are screwing me up. I keep getting 200 (not one of the answers), instead of 2 m/s.
The relevant passage material is, I an experiment involving conservation of momentum, a 10-g lead bullet with an initial speed of Vo=200 m/s is fired into a 1-kg block of wood at rest on a horizontal frictionless table of height D. The bullet embeds itself in the block and together the bullet/block slide off the table and land a distance R away from the base of the table.
The question is, What is the speed of the bullet/block immediately after the bullet embeds itself in the block? answer is 2 m/s
-the answer in the book suggests to me that .01 grams equal 1kg. What am I doing wrong?
This is in BR physics part I, page 210 question 30 passage V. Thanks in advance.
