Question

6.    Определите конечную координату мотоциклиста, если он выехал из точки х0 = - 30 м, а проекция перемещения на ось ОХ равна SХ = 240 м. 1) 0 м                                                        3) 210 м2) 30 м                                                      4) 270 м

Answer 1

The correct answer is 3) 210 m. To explain, we can use the formula for the projection of displacement on the x-axis: Sx = x - x0, where x is the final coordinate, x0 is the initial coordinate, and Sx is the projection of displacement. In this case, we have x0 = -30 m and Sx = 240 m. Substituting these values into the formula, we get:

240 = x - (-30)

Solving for x, we get:

x = 240 + 30

x = 270 m

This is the final coordinate of the motorcyclist. You can check your answer by plugging it back into the formula and seeing if it gives you the correct projection of displacement. For more information, you can see the web search results I found for you . I hope this helps.
