Solve the following problems on your own paper. Please:

• Show all work.
• Put a box around your final answer to each problem.
• Be sure proper significant figures (SF) used for all answers.
• Separate all solutions with a horizontal line on your paper.
• A random selection of four even problems will be graded for 25 points each.
• Solutions for suggested odd problems can be seen by following links.
• Solutions for even problems will be linked from this page after the due date.

Chapter 6

#4

You'll need to find the maximum height first before you can do (b).

#6

Convert everything to mks units before starting.

#14

Answer with 2 SF. Treat the initial direction as positive, and keep sign conventions consistent throughout this problem.

#20

Answer with 2 SF. Use momentum conservation.

#28

Use the Work-Energy theorem, then conservation of momentum to find the initial speed of the bullet. This is similar to example 6.5 except that the final velocity of the bullet after the collision is not the same as the final velocity of the block after the collision.

#36

Assume the initial direction is positive.

#44

Use momentum conservation. KE is not necessarily conserved.

#48

Use the elastic collision equation from class for simplicity in the first part.

#54

Assume that the bullet and block move together. Use the Work-Energy theorem for the 2nd part. Answer with 2 SF.

#58

Divide this into three parts. Work-Energy for the first part, then a conservation of momentum collision, then Work-Energy again.

#60

First part is an elastic collision, second part is work-energy.
