You will use this problem for Questions 5 and 6.  Read carefully!   A bullet, mb = 0.015 kg, is fired horizontally with a velocity of 800 m/s.  The bullet strikes a stationary wooden block, mw = 3.0 kg, that is hanging from a string.  The bullet embeds itself in the block of wood.  (see diagram below) Q5:  Find the speed of block and bullet immediately after the collision. Q6:  After the collision, what is the maximum height that they will reach, as measured from the block’s initial position? For this question, enter the answer to Q6.

You will use this problem for Questions 10 and 11 and a BONUS question.  Read carefully!   A block slides from rest down a frictionless ramp, where it then encounters a flat rough floor, mk = 0.55, as shown in the diagram below.  Q10: How fast is the block traveling when it reaches point A at the bottom of the ramp? Q11:  How much work is done by friction to bring the block to a stop? (BONUS) How far across the rough floor does it travel before coming to a stop? For this question, enter the answer to Q11.
