Answer:
R=19.5m
= 4.65° S of W
Explanation:
Refer the attached fig.
displacement of the x and y components
x-component displacement is () =
= A (20°) + B
(40°)
= -12.0(20°) + 20.0
(40°)
= -19.425m
x-component displacement is () =
= A (20°) - B
(40°)
= 12.0(20°) - 20.0
(40°)
= -1.579
resultant displacement
∴
R =
=
=19.5m
=
=
= 4.65° S of W
On comparing values , we see that student which has the largest percent error is <u>A. Student 4: 9.61 m/s2 .</u>
<u>Explanation:</u>
Here, we have Four students measured the acceleration of gravity. The accepted value for their location is 9.78m/s2. Let's calculate which student’s measurement has the largest percent error :
<u>A. Student 4: 9.61 m/s2 </u>
Percentage of error = %.
<u>B. Student 3: 9.88 m/s2 </u>
Percentage of error = %.
<u>C. Student 2: 9.79 m/s2 </u>
Percentage of error = % .
<u>D. Student 1: 9.78 m/s2</u>
Percentage of error = % .
On comparing values , we see that student which has the largest percent error is <u>A. Student 4: 9.61 m/s2 .</u>
