Compute all parts of given problem:
Problem: A rhinoceros is at the origin of coordinates at time t1 = 0. For the time interval fromt1 = 0 to t2 = 18.0 s, the rhino's average velocity has x-component -3.9 m/s and y-component 4.7 m/s.
Part A: At time t2 = 18.0 s, what are the x and y coordinates of the rhino?
x = ........m
y = .........m
Part B: How far is the rhino from the origin?
...........m
