**[University Physics] Finding kinetic energy given a**

In this video you will be shown how to calculate a velocity vector given a speed and a direction of motion.... Finding velocity vector based on angle and speed [closed] Ask Question 5. I am programming some movement for AI for a game based on angle and speed.Its a 2D program based on x,y axis. I currently have a position vector as-well as a velocity vector which accounts for speed and current direction of the AI.Every time I move the AI I just add the velocity vector to the current position to get my

**How to find average velocity given a position vector**

5/06/2017 · A boat s velocity, measured in meters per second, is described by vector b=(4, -3). In two or more complete sentences, explain how to find the speed of the boat and the direction it is traveling in standard position. In your final answer include all calculations.... 3/08/2009 · As far as I understand your problem, you are trying to find the component of the velocity in the direction of the unit vector. This is not the same thing as finding the velocity. This is not the same thing as finding the velocity.

Given vectors A and B, the cross product C is defined as the vector that 1) is perpendicular to both A and B (which is what you are looking for) 2) whose magnitude is th … e product of the magnitudes of A and B times the sine of the angle between them.... Resolving a vector means finding its magnitude in a particular direction. In the diagram above, the vector r has magnitude r and direction j to the x-axis. Using basic trigonometry, we can calculate that the component of r in the direction of the x-axis is rcos j .

**Calculating a velocity given speed and direction**

The significance of 'direction' can be seen in the difference between velocity and speed. In physics, speed is a pure scalar, or something with a magnitude but no direction --such as 5 m/s. 5 meters per second does not tell us which way the object is moving.... The speed mentioned in the previous chapter is the magnitude of the velocity vector ; is the component of the velocity along the trajectory, which can be either positive or negative. When vectors are used to describe the motion, and are simply called velocity and acceleration.

## How To Find Velocity Vector Given Speed And Direction

### While the actual direction of the object (and thus, of the velocity vector) is changing, its direction is always tangent to the circle. To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed.

- Print; We can be given a velocity in more than one way. One way is to be given a speed together with a bearing. The velocity can be found using trigonometry.
- In thomas calculus $12$ edition it gives the position vector along a line as $\vec r(t) = \vec r_0 + t\vec v$ where $\vec r_0$ is the initial position vector and $\vec v$ is the direction vector.
- 9/01/2017 · This video explains how to determine the velocity, speed, direction, and acceleration give a position vector-valued function. http://mathispower4u.com.
- These two equations tell us how to calculate the components of a vector, given its magnitude and direction. We need not restrain ourselves to the x and y axes: we can do this in any two or more perpendicular directions. This is a very important technique in analysing the forces acting on an object: we often wish to consider the forces acting in the direction of motion and at right angles to it
