[Ques. 2] A vector lies in the x-y plane. For what orientations will both components be negative?
1.The vector lies between 180 and 270 from the x-axis.
2.The vector lies between 0 and 90 from the x-axis.
3.The vector lies between 90 and 180 from the x-axis.
4.None. Just like for vector magnitudes, components are always positive.

[Ques. 6] You drop a ball from a window on an upper floor of a building. It strikes the ground with speed v. You now repeat the drop, but you have a friend down on the street who throws another ball upward at speed v. Your friend throws the ball upward at exactly the same time that you drop yours from the window. At some location, the balls pass each other. Which of the following is true?
1.This location is below the halfway point between the window and the ground.
2.This location is at the halfway point between the window and the ground.
3.This location is above the halfway point between the window and the ground.
4.One cannot tell which of these choices is correct from the information given.
[Ques. 7] An object falls freely from a height, H. It is released at t = 0 and strikes the ground at t = T. Consider the time at which the object is at a height of H/2. Also consider the height at which the object is located at the time T/2. Which of the following is true?
1.When the object is at a height H/2, the time is less than T/2 and when the time is T/2, the object is at a height of less than H/2.
2.One cannot tell which of these choices may be true from the given information.
3.When the object is at a height of H/2, the time is equal to T/2.
4.When the object is at a height H/2, the time is greater than T/2 and when the time is T/2, the object is at a height of more than H/2.
[Ques. 8] Ball A is thrown up and Ball B is thrown down, both with the same initial speed. Neglecting air resistance, just prior to hitting the ground, which of the following is true?
1.You cannot tell which has the greater speed because it depends on the value of the initial speed.
2.Ball A's speed is greater than Ball B's speed.
3.They have the same speed.
4.Ball B's speed is greater than Ball A's speed.
[Ques. 9] Jordan throws a marble upward with a speed vi , while Marisa drops a marble at the same instant. While they are in flight, which of the following is true?
