• 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
