Chapter 4, Problem 2OQ

Entering his dorm room, a student tosses his book bag to the right and upward at an angle of 45° with the horizontal (Fig. OQ4.2). Air resistance does not affect the bag. The bag moves through point Ⓐ immediately after it leaves the student’s hand, through point Ⓑ at the top of its flight, and through point © immediately before it lands on the top bunk bed. (i) Rank the following horizontal and vertical velocity components from the largest to the smallest. (a) v_Ⓐx (b) v_Ⓐy (c) v_Ⓑx (d) v_Ⓑy (e) v_©y. Note that zero is larger than a negative number. If two quantities are equal, show them as equal in your list. If any quantity is equal to zero, show that fact in your list. (ii) Similarly, rank the following acceleration components. (a) a_Ⓐx (b) a_Ⓐy (c) a_Ⓑx (d) a_Ⓑy (e) a_©y.
