1. Assuming that a rabbit runs at a speed of 12.0 meters per second. How far would the rabbit travel in 11.5 seconds? 12.0 m 1 s X 11.5 s = 138 m 2. A hiker takes a hiking trip around the camp. He first travels 5.10 km in one hour at a constant speed. He then travels 16.5 km in two hours at a different constant speed and reaches a ranch tower. What is the average speed of the hiker for the entire trip? 16.5 5.10 km 2 hr 1 hr = 11.4 km 1 hr 3. A tortoise and a hare engage in a race. A tortoise can run with a speed of 0.15 m/s. A hare can run 25 times as fast as the tortoise. In the race, they start at the same time; however, the hare being very proud of his much higher speed stops for a nap for 5.0 minutes. The tortoise wins the race by 35 cm. (a) What is the length of the race? (b) How long does the race take? t tortoise = L v = L 0.15 m / s 4. A car starts at rest and accelerates with an acceleration of 4.51 m/s 2 . After the car travels a distance of 355 m, it slows down with an acceleration of -2.34 m/s 2 until its speed reaches 25.4 m/s. What is the total displacement of the car?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
