Question

Parts A, B, and C please

(Figure 1) If F = {350i - 250j - 450k} N and cable AB is 15 m long, determine the x,y, z coordinates of point A. Determine the x coordinates of point A. Express your answer to three significant figures and include the appropriate units. Determine the y coordinates of point A. Express your answer to three significant figures and include the appropriate units. Determine the 2 coordinates of point A. Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

F=350i-250j-450k

let x coordinate be a

and y coordinate be b

and z coordinate be c

so position is ai+bj+ck

so where a^2+b^2+c^2=15^2=225

and 350/a=-250/b=-450/c=k

a=350/k b=-250/k and c=-450/k

putting in equation we get

(350^2+250^2+450^2)/k^2=225

so k=41.49

so a=350/k=8.43 part A

b=-250/k=-6.025 part B

c=-10.845 part C
