Hopefully this works as a place to talk about study groups and problems we're having in 2211

    Problem 62, Chapter 5, Page 134

    Does anyone have the answer for Prob 62 in Ch 5.

    I think I did everything right, but my total time seems a little too short.

    I can post my answer, but my total time from the top of the incline to the floor is .799 seconds.


    My answers:

    a: Acceleration is 4.9 m/s^2
    b: Final Velocity is 3.13 m/s
    c: Distance from table where object hits .3344m
    d: Total time = .799s
    e: In this problem mass does not matter. It would matter IF we accounted for friction.

    My answers are:

    a: Acceleration a: 4.9 m/s^2
    b: Final Velocity: 3.13 m/s
    c: Distance R: 2.22m
    d: Total Time = 1.46s
    e: Mass does not affect the above calculations.

    Well, I have no idea if these are right or not. Just my calculations. scratch
