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?

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.

(8 points) For the word problems given below,Classify each problem as:   23×34   or       34×23       or       23÷34    or        34÷23     or         34-23        or        none of theseYou may use some expressions multiple times or not at all.Explain your choice of expression for each problem.Solve each problem (no pictures or explanations necessary unless you want it to help you solve the problem). Include units with all your solutions. a. If there is 34 of a bag of grass seed left and you pour out 23 of that grass seed, then how much of a bag of grass seed did you pour out?b. If there is 34 of a bag of grass seed left and you pour out 23 of a bag of grass seed, then how much of a bag of grass seed is left after that?c. If 34 of a bag of grass seed weighs 1 pound, then how much does 23 of a bag of grass seed weigh?d. If 23 of a bag of grass seed weighs 34 of a pound, then how much does 1 bag of grass seed weigh?  Question: I have written my answer to this question on paper. Type yes or no. 

I acknowledge that I have read the syllabus and understand the requirements for this course.

I acknowledge that all uploaded assignments must be scans of handwritten work on paper and in the format of a single PDF file that is readable (i.e. not corrupted), multipage (if more than one page is needed), portrait (as opposed to landscape), rotated correctly (i.e. not upside down or sideways), and legible (written dark enough and clearly).
