So couldn't read the previous tutors question sadly. probably threw it into a equation graphic. I CAN'T READ GRAPHICS LIKE THAT since I am blind. So here is the question again: , a with right arrow above = 5b where B⃗ = 8 i^− 8 j^

1. A =3i - 9j

B = -4i + 2j

A.B = -12 - 18 = -30

2. A = 5i + 5j

B = 2i - 4j

A.B = 10 - 20 = -10

3. A = 8i + 4j

B = 41 - 8j

A.B = 32 - 32 = 0

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
