Below is a “clean” copy of Quiz 3. I’ve decided the problem for revision will be the last question, #4
“A thrown rock has an initial velocity of 35 m/s directed at an angle 25 degrees above horizontal. What is its velocity 2.0 seconds later? Neglect air drag and note that the rock experiences a constant acceleration of 9.8 m/s2 downward. (You may express this either in components or as a magnitude and direction.)”
Ordinarily I collect the revisions and corrections with the next quiz, but because this is going up late and because the next physics quiz is Tuesday, revisions will be due on Thursday this week.
