COMPUTER SCAN SHEET STUDENT INSTRUCTIONS: IT IS YOUR RESPONSIBILITY TO
ENSURE THAT THE ANSWER SHEET IS PROPERLY COMPLETED. YOUR EXAMINATION
RESULT DEPENDS UPON PROPER ATTENTION TO THESE INSTRUCTIONS.
The scanner, which reads the sheets, senses the bubble shaded areas by their non-reflection of light. A heavy
mark must be made, completely filling the circular bubble, with an HB pencil. Marks made with a pen or felt-
tip marker will NOT be sensed. Erasures must be thorough or the scanner may still sense a mark. Do NOT use
correction fluid on the sheets. Do NOT put any unnecessary marks or writing on the answer sheet.
1. Print your name, student number, course name, section number, instructor name, and the date in the
spaces provided at the top of Side 1 (red side) of the sheet. Then you MUST sign the sheet in the space marked
SIGNATURE.
2. Mark your student number in the space provided and fill in the corresponding bubble numbers
underneath.
3. Mark only ONE choice from the alternatives (a, b, c, d, e) provided for each question. The question
number is to the left of the bubbles. Make sure that the number of the question on the scan sheet is the same as
the question number on the test paper.
4. Pay particular attention to the Marking Directions on the form.

Make absolutely sure to fill out the bubble in the version column appropriate for your version of the mid-
term exam.

B. 1 m/s south, inelastic
C. 1 m/s south, perfectly(completely) inelastic
D. 1 m/s north, inelastic

long and is sloped at an angle of 28 relative to the horizontal. If the average force of friction on her skis is
12 N, calculate the speed with which she collides with a snowbank at the bottom of the hill.
