16 Questions | Total Attempts: 177  Settings  Please take this quiz to show how much you have learned in this unit. Please note: each multiple choice question is followed by a question asking you to explain your answer to the previous question. You must explain how you arrived at your answer; tell me what you know and how you figured out the answer and then I will understand better what you know and can do.

Look at the diagram below of an arrow being shot horizontally from a bow and another being dropped from the same height. Arrow A is shot horizontally at 50 m/s. Arrow B is dropped at the exact same instant that Arrow A leaves the bow. Neglecting air resistance, how does the time Arrow A takes to hit the horizontal plane in the diagram compare with the time Arrow B takes to strike the same horizonatal plane?
• 7.
Use scientific language and your understanding of projectile motion to prove that a 100 mi/h pitch thrown horizontally by a major league player will hit the ground in the same amount of time as a 10 mi/h pitch thrown horizontally from the same height by a child.

Farther toward the back of the cabin depending upon the plane’s speed

• B.

Farther toward the front of the cabin depending on the plane’s speed.

• C.

Right back down on the person who tossed it straight upward.

• D.

Farther toward the back of the plane if the ball is light, but farther toward the front if the ball is heavy Back to top
