Example Questions

Example Question #901 : Spatial Calculus

Which of the following vectors is perpendicular to ?

Possible Answers:

Correct answer:

Explanation:

By definition, a given vector  has a perpendicular vector . Therefore, the vector perpendicular to  is .

To verify that two vectors are perpendicular their dot product must equal zero.

The dot product is as follows.

Substituting in our vector values we get:

Example Question #902 : Spatial Calculus

Which of the following is perpendicular to the vector ?

Possible Answers:

Correct answer:

Explanation:

By definition, a given vector  has a perpendicular vector .

Given a vector , its perpendicular vector will be .

We can further verify this result by noting that the product of two perpendicular vectors is

Since , then   is perpendicular to .

Explanation:

By definition, a given vector  has a perpendicular vector .

Given a vector , its perpendicular vector will be .

We can further verify this result by noting that the product of two perpendicular vectors is

Since , then  is perpendicular to .

Example Question #51 : How To Find Position

At time  a particle is at the origin at rest with no velocity. It then experiences an acceleration of

.

After  seconds, what is the particle's position?

Possible Answers:

Correct answer:

Explanation:

First, we integrate  with respect to  to get velocity:

We know that the particle is not moving at , so

.

Solving this gives us

.

Now, we have to solve for position. To do this, we integrate  with respect to . Thus, we get

.

We know that the particle starts at the origin, so we have to solve:

This implies that , so we have:

.

As a special case:

.

Example Question #905 : Spatial Calculus

Given the initial velocity, initial position and acceleration of an object, find its position function.

Possible Answers:

Correct answer:

Explanation:

We begin by integrating the acceleration function and using the initial condition to find the value of the constant of integration:

Now that we have the velocity function we repeat the process to find the position function:

Example Question #906 : Spatial Calculus

Which of the following is perpendicular to the vector ?

Possible Answers:

Correct answer:

Explanation:

By definition, a given vector  has a perpendicular vector . Given a vector , we therefore know its perpendicular vector is .

We can further verify this by noting that the product of a vector and its perpendicular vector is .

Since , the two vectors are perpendicular to each other. 

Example Question #907 : Spatial Calculus

Which of the following is perpendicular to the vector ?

Possible Answers:

Correct answer:

Explanation:

By definition, a given vector  has a perpendicular vector . Given a vector , we therefore know its perpendicular vector is .

We can further verify this by noting that the product of a vector and its perpendicular vector is .

Since , the two vectors are perpendicular to each other.
