If not, have you attempted the question?
3. I don’t understand how to answer the question using the information I’ve been given
4. Are you happy with how to use direction and velocity as vectors? (In terms of i and j)
5. I think so yes

You need to find a unit vector in his direction of travel and then mutiply it by 5 - velocity has magnitude and direction.
