The entire walk takes you 30 seconds. If you are calculating average speed, you would calculate the entire distance (3 + 4 + 3 + 4 = 14 meters) over the total time, 30 seconds. From this, you would get an average speed of 14/30 = 0.47 m/s. When calculating average velocity, however, you are looking at the displacement over time.
It takes into account how fast the car is going (50 mph) and the direction (west). To calculate velocity, we replace the scalar quantity of distance travelled with the vector quantity of displacement. This allows us to get the value of velocity, with the equation: Do not confuse the S in both equations. In the speed equation, S mean speed.
6 kwi 2016 · I don't think that will be possible. If my understanding of accelerometers is correct, they measure acceleration. Then you have a situation when the speed is constant. Acceleration = 0, according to Newton's laws. You would have to keep track of changes in acceleration then perform math to maintain the state.
6 dni temu · To find the angle that maximizes the horizontal distance in the projectile motion, follow the next steps: Take the expression for the traveled horizontal distance: x = sin(2θ) × v²/g. Differentiate the expression with regard to the angle: 2 × cos(2θ) × v²/g. Equate the expression to 0 and solve for θ: the angle which gives 0 is 2θ = π ...

By the end of this lesson you will be able to: Distinguish between scalar and vector quantities. Distinguish between distance and displacement. Distinguish between speed and velocity. Distinguish between average speed and instantaneous speed. Convert between metres per second and kilometres per hour. (Header image: Laurin Rinder, Adobe Stock)
3 dni temu · The equation for the distance traveled by a projectile being affected by gravity is sin(2θ)v 2 /g, where θ is the angle, v is the initial velocity and g is acceleration due to gravity. Assuming that v 2 /g is constant, the greatest distance will be when sin(2θ) is at its maximum, which is when 2θ = 90 degrees.
