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_.

Consider a point particle with position vector r = (x, y, z) in Cartesian coordinates, moving with a velocity v = (β, αz, −αy), where α and β are positive constants. (a) What are the physical dimensions of α and β? (b) Find the general form of r(t), the position of the particle, as a function of time t, assuming the initial position of the particle is r0 = (0, 2, 0) (hint: write v = (β, αz, −αy) as a system of first order ODEs and note that the equation for x is decoupled from the others). Describe in words the motion of the particle and sketch its trajectory in R3 (you can use software packages for the plot). (c) Show that the speed of the particle is constant, but the acceleration vector a(t) is nonzero. Justify. Assuming the particle has a constant mass m, use Newton’s second law to show that the force acting on the particle is (as a function of the position r = (x, y, z)) F(x, y, z) = mα2(0, −y, −z).
