Unformatted text preview: tn PHYS 122 EXAM 1 October 1, 2009
Prof. S.M. Bhagat Name: 52’}; L a '1'th (Sign in ink, print in pencil) Notes 1. There are six (6) problems in this exam. Please make sure that your copy has all of
them. ' 2. Please show your work, indicating clearly what formula you used and what the
symbols mean. Just writing the answer will not get you full credit. Instating vectors,
give both magnitude and direction. 3. Write your answers on the sheets provided. 4. Do not forget to write the units. 5. Do not hesitate to ask for clariﬁcation at any time during the exam. You may buy a formula at the cost of one point. Take Care! God Bless You! [“0 2 477x104 T—me
