A hiker travels 22.5 km at 45.0 degrees in 10.0 hrs on day one,18.0 km at 75.0 degrees in 9.50 hours on the second day, and 13.0km at 130.0 degrees in 7.50 hrs on the third day.
a) Find the resultant displacement, in magnitude and directionform, for the hiker.
b) Calculate the average speed the hiker has for the trip (don'ttake into account rest time).
c) Calculate the average velocity the hiker has for the trip(don't take into account rest time).
d) If the hiker traveled on a fourth day, what displacement mustthey make to have a resultant displacement displacement of 50.0 kmat 90.0 degrees for all four day travel?
