    Start with #1-10. I'll be adding more by this weekend.

    Scratch #10. Here are the rest. 11, 17, 18, 20, 22, 23, 25, 27, 29-34, 36, 39, 49, 52, 56, 67, 84

    A total of 30 problems - due by Monday, November 6th (exam day). You are free to do more for practice - exam MC questions will be similar.

    There will be one, multi-part FRQ on the exam, as well. We will have plenty of time to work on these in class between now and then..

     

    Answers as promised. Be sure to show your work for credit on the study guide problems. Just circling answers is just wrong...

    PHYS Kinematics Retake Practice

     

     

    Here are three example 2D kinematics-type problems where the projectile is launched at an angle:

     

    51. A football is kicked with an initial velocity of 25.0 m/s at an angle of 35.0 degrees with the horizontal. Determine the time of flight.

     

    52. A ball is launched into the air at an angle of 32.0 degrees to the horizontal with an initial speed of 18.0 m/s. Determine the horizontal distance.

     

    53. A baseball was hit at 45 m/s at an angle of 55° above the horizontal. How long did it take to reach the top of its peak?

     

    ANSWERS

    51) 2.92 s        52) 29.8 m          53) 3.8 s
