gaitons Set 1, Due Fri, Jan 18, 2008 at 23:59 1. 1 . [1 point, 10 tries] Larry leaves home at 4:03 and runs at a constant speed to the lamppost. He reaches the lamppost at 4:11, immediately turns, and runs to the tree. Larry arrives at the tree at 4:26. What is Larry's average velocity during his trip from home to the lamppost, if the lamppost is 387.0 m west of home, and the tree is 611.0 m east of home? Answer: -4.84e+01 m/min 2. 2 . [1 point, 10 tries] What is the average velocity for Larry's entire run? Answer: 2.66e+01 m/min 3. 3 . [1 point, 10 tries] The velocity graph of a particle moving along the x-axis is shown. The particle has zero velocity at t =0.00 s and reaches a maximum velocity, v max , after a total elapsed time, t total . If the initial position of the particle is x 0 =8.84 m, the maximum velocity of the particle is v max =13.7 m/s, and the total elapsed time is t total =16.9 s, what is the particle's position at t =11.3 s? Answer: 6.06e+01 m 4.

4 . [1 point, 10 tries] At t =11.3 s, what is the particle's velocity? Answer: 9.16e+00 m/s 5. 5 . [1 point, 10 tries] At t =11.3 s, what is the particle's acceleration? Answer: 8.11e-01 m/s^2 6. 6 . [1 point, 10 tries] A rock is tossed straight up with a velocity of 39.7 m/s. When it returns, it falls into a hole 19.8 m deep.

### What students are saying

• 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.
