Chapter 2.6, Problem 6EYU
A submerged alligator swims directly toward two unsuspecting ducks. The equation of motion of the alligator is xa = (0.25 m/s2) t2, the equation of motion of duck 1 is xd1 = 3 m − (1.5 m/s)t, and the equation of motion of duck 2 is xd2 = 3 m + (1 m/s) t. Which duck does the alligator encounter first?

- I have no idea to how to start to this question: Wags (a dog) decides to go on a journey. He begins his journey by traveling 58 meters in a direction directly south. He then runs 100.0 meters in a direction 30◦north of west. During the last leg of his journey, he follows a scent for 59 meters in a direction 30◦east of north. What distance does Wags end up from his initial startingpoint?arrow_forwardYou take a three-day hike. On the first day, you travel 5.0 km heading east. On the second you enjoyed the scenery so much you forgot to take note how far you have walked and in what direction. On the third day, after wandering for 8.5 km and in the direction 370 south of west, you found yourself in the base camp. Determine your displacement during the second day of your trip. Use the scale 1.0 cm : 2.0 km.arrow_forwardIn physics, we distinguish the terms "speed" and "velocity" based on whether the quantity is scalar or vector. Choose the correct statement on speed and velocity. They are both vector quantities. They are both scalar quantities. Speed is a vector quantity, and velocity is a scalar quantity. Speed is a scalar quantity, and velocity is a vector quantity.arrow_forward
