Answer to Problem 39PQ

The vector A in component form is A=(15.0i^6.00j^3.00k^)m_.

Explanation of Solution

Write the expression to find the component form of any vector.

    A=xi^+yj^+zk^

Here, x is the x component of the vector, y is the y component of the vector and z is the z component of the vector.

Conclusion:

Substitute 15.0m for x, 6.00m for y and 3.00m for z in the above equation.

    A=(15.0m)i^+(6.00m)j^+(3.00m)k^=(15.0i^6.00j^3.00k^)m

Therefore, the vector A in component form is A=(15.0i^6.00j^3.00k^)m_.

(b)

To determine

The vector B in component form having one-third the length of vector A but in the same direction of the vector A.

Answer to Problem 39PQ

The vector B in component form having one-third the length of vector A but in the same direction of the vector A is B=(5.00i^2.00j^1.00k^)m_.

Explanation of Solution

Write the expression to find the vector B.

    B=13A

Conclusion:

Substitute (15.0i^6.00j^3.00k^)m for A in the above equation.

    B=13((15.0i^6.00j^3.00k^)m)=(5.0i^2.00j^1.00k^)m

Therefore, the vector B in component form having one-third the length of vector A but in the same direction of the vector A is B=(5.00i^2.00j^1.00k^)m_.

(c)

To determine

The vector C in component form having thrice the length of vector A but in the opposite direction of the vector A.

(c)

Expert Solution

Answer to Problem 39PQ

The vector C in component form having thrice the length of vector A but in the opposite direction of the vector A is C=(45.00i^+18.0j^+9.00k^)m_.

Explanation of Solution

Write the expression to find the vector C.

    C=3A

Conclusion:

Substitute (15.0i^6.00j^3.00k^)m for A in the above equation.

    C=3((15.0i^6.00j^3.00k^)m)=(45.00i^+18.0j^+9.00k^)m

Therefore, the vector C in component form having thrice the length of vector A but in the opposite direction of the vector A is C=(45.00i^+18.0j^+9.00k^)m_.
