Unit A Assessment

 

A student standing on the top of a cliff shoots an arrow from a height of 30.0 m at 25.0 m/s and an initial angle of 32.0° above the horizontal. Show all your work in calculating the answers to the following questions. You may check your work using any of the simulations you have previously used in Unit A.

  1. What will be the horizontal and vertical components of the arrow’s initial speed?

  2. How high above the landscape under the cliff will the arrow rise? Assume a level landscape.

  3. How far off course will the arrow be after 3.35 s if there is a 12.0 m/s crosswind?

  4. What will be the speed and angle of flight of the arrow 3.35 s after release if there is no crosswind?

Submit your answers to the Unit A Assessment to your teacher for marks.
