Chapter 1 2D Problem Set Knowledge: I Thinking/Inquiry: / Communication: 15 Application /15 1. An object moves 60.0 m [E 75.0 N] and then 50.0 m [E 45.0 S]. a. Determine the object's total displacement using graphing scaled diagram. " /5 marks) b. Determine the object's total displacement using component method. (A /5 marks) c. Determine the object's total displacement using sine and cosine law. (A /4 marks) 2. In Figure, a bird changes direction in 2.8 s while flying from point 1 to point 2. Determine the bird's average acceleration. Hint: Use component method. (A /6 marks) V2 = 8.5 m/s [E 30.00 N] Vi = 6.4 m/s [E 30.0' S]
