Question

Can you explain this? I already understand the component method, but I want to know how to find it by using the graphical method. Why the displacement is 20 m and the angle is 0 degrees???

A basketball player runs down the court, following the path indicated by the vectors A, B, and C in the figure below. The magnitudes of these three vectors are A = 10.0 m, B = 20.0 m, and C = 7.0 m. Find the magnitude and direction of the net displacement of the player. Estimate the solution using the graphical method. Displacement ~ 20 m Angle ~ 0 degree Calculate an accurate solution using the analytical component method. Does your answer agree with the result of ? Define a coordinate system where the x-axis increases to the right and the y-axis is toward the top of the page.

Explanation / Answer

it was just approximated to those values ... as 1.7 is a very small angle in this case so is 0.6^2
