Question 2

Two forces exerted on a block as shown in the figure below. What is the horizontal component of the net force?
  [Figure: A rectangular block is shown. From its top-left corner, a force vector of magnitude 50 N is directed upward and to the left, making an angle of 53° with the horizontal line extending to the left. From its top-right corner, a force vector of magnitude 20 N is directed upward and to the right, making an angle of 37° with the horizontal line extending to the right.]

Accepted Answer

14 N, West

Answer

70 N, East

Answer

30 N, West

Answer

28 N, West

Question 3

Accepted Answer

7,13 m/s

Answer

16.6 m/s

Answer

12.8 m/s

Answer

7.07 m/s

Question 4

Let \vec{C}=\vec{A}	ext{X}\vec{B} and 	heta 
eq 90^0, where 	heta is the smaller angle between \vec{A} and \vec{B} when they are drawn with their tails at the same point. Which of the following is NOT true?

Accepted Answer

\vec{A}.\vec{B} = 0

Answer

\vec{A}.\vec{C} = 0

Answer

/\vec{C}/=/\vec{A}//\vec{B}/ \sin 	heta

Answer

-\vec{C}=\vec{B}	ext{X}\vec{A}

Question 5

Accepted Answer

20 m

Answer

400 m

Answer

10 m

Answer

40 m

Question 6

Which of the following is correct about the motion shown in the velocity – time graph below?
  [Figure: A velocity-time graph showing velocity v(m/s) on the vertical axis and time t(Sec) on the horizontal axis.
- Vertical axis has markings from 2 to 14 in increments of 2.
- Horizontal axis has markings A, 2, 4, 6, 8, 10, 12, 14.
- A straight line starts at the origin A(0,0) and rises to point B(2,4), with dashed lines indicating t = 2 and v = 4.
- From B(2,4), a steeper straight line rises to point C(3,12), with a dashed horizontal line extending to v = 12.
- From C(3,12), a horizontal line segment connects to point D(6,12).
- From D(6,12), a straight line descends to point E(12,0) on the horizontal axis.]

Accepted Answer

Total displacement is 84m.

Answer

Between C and D, the motion is with constant acceleration.

Answer

Between B and C, the acceleration is 4	ext{m/s}^2

Answer

Between D and E, the motion is with constant positive acceleration.
