HW02 General reminder : Do not forget to specify the CS used in each problem solution. 1. Wolfson, Ch. 2 #22. e) Calculate the instantaneous velocity at each integer time on the interval. 2. Wolfson, Ch. 2 #23. Change 𝑏 = 82 𝑚 / 𝑠 to 𝑏 = 146 𝑚 / 𝑠 . c) Determine the rocket acceleration as a function of time. d) Find the rocket height, velocity, and acceleration vectors at 1.27s after launch. e) When is the rocket at 15.3m? f) At what time does the rocket return to its launch position? 3. Wolfson, Ch. 2 #32. 4. Wolfson, Ch. 2 #39. Do not neglect the sound travel time.

Wolfson, Ch. 3 #28. b) What is the tip’s instantaneous velocity vector at this final position? 8. Wolfson, Ch. 3 #34. c) Assuming you initially launched your boat perpendicular to the river, how far ‘downriver’ does your boat land at the opposite side of the river? 9. Wolfson, Ch. 3 #52. d) Repeat b) and c) for acceleration instead of velocity. 10. Wolfson, Ch. 3 #54....
