A positron undergoes a displacement Δ. 8.0i-45 ^ + 4 ok, ending with the position vector r-8.5i 7 ok n meters what was the positron's on er posit on vecto The displacement vector is equal to the subtraction of the initial position vector from the final position vector. You want the initial position vector Vectors are to be combie axis alone. Then combine y components alone. Finally, combine z components alone.

Answer 1

Since ΔR=R2−R1, we may let the initial position vector be →R=xˆi+yˆj+zˆkand then compare terms to write

x−0=8⇒x=8

8.5−y=−4.5⇒y=13

−7−z=4⇒z=−11

∴R1=8i+13j−11k
