Question

particle starts from origin and moves with a constant velocity v = 2i+3j find the position after 2sec​

Answer 1

Answer:

(4,6)

Explanation:

For these kind of 2D problems, treat them independently in two separate 1D problem in perpendicular directions.

What is displacement if velocity is constant; it is velocity*time. Apply the same in both x and y. Suppose the velocity is Vx in x direction and Vy in y direction, which is constant in this case.
