all of the following questions: 1.) A flinch rides in the back of Galapagos tortoise, which walks at the stately pace of 0.060 m/s. After 1.5 minutes, the flinch tires of the tortoise's slow pace, and takes in the same direction for another 1.4 minutes at 11 m/s. What was the average speed of the flinch for this 2.9 minute interval? 2.) To visit your favorite ice cream shop, you must travel 430 m west on Main Street and then 970 m south on Division Street. Suppose you take 49 s to complete the 430 m displacement and 79 s to complete the 970 m displacement. a) What is the magnitude of your average velocity during the 128- second period of time? b) What is the direction of your average velocity during this 128- second period of time? c) What is your average speed during the trip? 3.) You drive a car 1500 ft to the east, then 2600 ft to the north. The trip took 3.5 minutes. a) What was the direction of your average velocity? b) What was the magnitude of your average velocity? 4) At the starting gun, a runner accelerates at 1.70 m/s^2 for 4.50 s. The runner's acceleration is zero for the rest of the race. a) What is the speed of the runner at t = 2.0 s? b) What is the speed of the runner at the end of the race
