A  4 . 00   g  bullet is moving horizontally with a velocity of  355   m / s  to the right. The bullet is approaching two blocks resting on a horizontal frictionless table of height  25 . 0   c m  above the ground. Air resistance is negligible. The mass of the first block is  1150   g , and its velocity is  0 . 550   m / s  after the bullet passes through it. The mass of the second block is  1530   g . If the bullet passes completely through the first block and embeds itself in the second one, as indicated in Fig. 4.1, (a) what is the velocity of the second block after the bullet embeds itself and (b) what is the ratio of the total kinetic energy of the bullet-blocks system after the collision to the one before the collision? If the bullet passes completely through both blocks and moves with a velocity  50 . 0   m / s  after leaving the second block, as indicated in Fig. 4.2, (c) what is the velocity of the second block after the collision? After the bullet leaves the two blocks, the first block collides with the second block and moves with a velocity  0 . 200   m / s  after the collision (see Fig. 4.2), (d) what is the velocity of the second block after the collision with the first block? The second block eventually leaves the table and falls to the ground, (e) what is the speed of the second block right before it hits the ground? final_fig4_q20_spr2026.docx

A 10. kg block on a rough horizontal surface is attached to a light spring (spring constant k=1.6×103 N/m). The block is pulled 8.0 cm to the right from its equilibrium position and released from rest. The frictional force between the block and surface has a magnitude of 30. N. What is the kinetic energy of the block as it passes through its equilibrium position?

A jet airliner moving at 500. mph due east moves into a region where the wind is blowing at 120. mph in a direction 30.0° east of north. What are the magnitude and direction of the new velocity of the aircraft relative to the earth?

(5 points)Label all of the tick marks on the number lines shown below appropriately (so that the long and short tick marks fit with the structure of the base-ten system) and explain in detail why you labeled them that way. Question: I have written my answer to this question on paper. Type yes or no. 

Multiple Choice: No work or explanation needed.0÷5=

Various question formats are used on this exam. None will require written answers. Choose the best answer for each question. You may use any number of pages from your notes or PowerPoint files from the course to help you. These may be digital or on paper. I recommend using files in Microsoft PowerPoint, Word, or Pages, or PDF files to make sure Honorlock will allow them. You will have 90 minutes to answer all of the questions once you begin. Questions and answers are presented at random.
