Given

A = (2.22cos 24.2°î + 2.22 sin 24.2°3) m

B = (2.223) m

PART A:

C = A + B

ChemistryExplain “#213 The displacement vectors A with arrow and B in Physics, Ap physics 1 practice test, Best colleges for physics, Best physics bo

C = (2.22 cos 24.2° +2.22 sin 24.2°3) + (2.22;)

C = (2.22 cos 24.2°î + 2.22 (1 + sin 24.2°)

The magnitude of the resultant vector is

a =(2.22 cos 24.20)2 + (2.22 (1 + sin 24.2°)2) = 3.73 m

And the direction of the resultant vector is

1/2.22(1+ sin 24.2°) 0 = tan-1 2.22 cos 24.2° =5710

PART B:

C = A-3

C = (2.22 cos 24.2°î +2.22 sin 24.2° 2.22

$\vec C=\left (2.22\cos24.2^o\hat i+2.22\left (\sin24.2^o -1\right )\hat j \right )$

The magnitude of the resultant vector is

= ((2.22 cos 24.20)2 + (2.22 (sin 24.29 – 1))?) = 2.41 m

And the direction of the resultant vector is

-1 0 = tan- 2.22 (sin 24.2° - 1) 2.22 cos 24.2° = -32.9° = (360° -32.9°) = 327.1°

Both the answers are equivalent and correct for the angle.

PART C:

$\vec C=\vec B-\vec A$

ChemistryExplain “#213 The displacement vectors A with arrow and B in Physics, Ap physics 1 practice test, Best colleges for physics, Best physics bo

$\vec C=\left (2.22\hat j \right )-\left (2.22\cos24.2^o\hat i+2.22\sin24.2^o\hat j \right )$

$\vec C=\left (-2.22\cos24.2^o\hat i+2.22\left (1-\sin24.2^o \right )\hat j \right )$

The magnitude of the resultant vector is

$\left |\vec C \right |=\sqrt{\left (\left (-2.22\cos24.2^o \right )^2+\left (2.22\left (1-\sin24.2^o \right ) \right )^2 \right )}=2.41\ m$

And the direction of the resultant vector is (it is in 2nd quadrant)

(2.22(1 - sin 24.2°) 0 = 180° + tan-1 -2.22 cos 24.20 = 180° - 32.9° = 147.1°

PART D:

$\vec C=\vec A-2\vec B$

ChemistryExplain “#213 The displacement vectors A with arrow and B in Physics, Ap physics 1 practice test, Best colleges for physics, Best physics bo

$\vec C=\left (2.22\cos24.2^o\hat i+2.22\sin24.2^o\hat j \right )-\left (2\times 2.22\hat j \right )$

$\vec C=\left (2.22\cos24.2^o\hat i+2.22\left (\sin24.2^o -2\right )\hat j \right )$

The magnitude of the resultant vector is

$\left |\vec C \right |=\sqrt{\left (\left (2.22\cos24.2^o \right )^2+\left (2.22\left (\sin24.2^o-2 \right ) \right )^2 \right )}=4.07\ m$

And the direction of the resultant vector is

$\theta=\tan^{-1}\left ( \frac{2.22(\sin24.2^o-2)}{2.22\cos24.2^o} \right )=-60.2^o\equiv (360^o-60.2^o)=299.8^o$

Both the answers are equivalent and correct for the angle.
