1. A dolphin is initially swimming at 7.2 km/hr, directly West. 7 seconds later, the dolphin is swimming 5.3 km/hr, 30° W of N. What was the dolphin's acceleration? (Use graphical addition or subtraction to make an estimate before doing any calculations. Compare the result of your calculations to the graphical addition or subtraction to determine if your answer is reasonable.)
