Finding the Scalar Triple Product of Three Vectors

In summary, to find the value of m that will result in a volume of 24 for a parallelopiped with edges given by (2î + 3j^+ 4k^), 4j^, and (5j^ + mk^), you can use the formula for the scalar triple product of three vectors. This formula is not the same as the dot product of three vectors.

Homework Statement


The edges of a parallelopiped are given by the vectors (2î + 3j^+ 4k^), 4j^ and (5j^ + mk^). What should be the value of m inorder that the volume of the parallelopiped be 24?

Homework Equations

The Attempt at a Solution


Volume of the parallelopiped is the scalar triple product of three vectors. I want to know the formula or method of finding dot product of three vectors.

The scalar triple product is not a dot product of three vectors, it is ##\vec u \cdot (\vec v \times \vec w)##.

1. What is motion in a plane?

Motion in a plane refers to the movement of an object in two-dimensional space, along the x and y axes. This includes both linear and rotational motion.

2. How is motion in a plane different from motion in a straight line?

Motion in a plane involves movement along two axes, while motion in a straight line only involves movement along one axis. In other words, motion in a plane is two-dimensional, while motion in a straight line is one-dimensional.

3. What is the difference between velocity and speed in motion in a plane?

Velocity refers to the rate of change of an object's position in a specific direction, while speed refers to the rate of change of an object's position regardless of direction. In other words, velocity is a vector quantity, while speed is a scalar quantity.

4. How are vectors used in analyzing motion in a plane?

Vectors are used to represent both the magnitude and direction of an object's motion in a plane. They can also be used to calculate the resultant velocity and acceleration of an object.

5. Can motion in a plane be described using equations?

Yes, motion in a plane can be described using equations such as the equations of motion, which relate velocity, acceleration, time, and displacement. These equations can also be used to solve for unknowns in a motion in a plane problem.
