A rhinoceros is at the origin of coordinates at time t1 = 0. For the time interval from t1 to t2 = 14.5s, the rhino's average velocity has x-component -4.2 m/s and y-component 4.5 m/s.
At time t2 = 14.5 s what is the x-coordinate of the rhino?
At time t2 = 14.5 s what is the y-coordinate of the rhino?
How far is the rhino from the origin?
plz help anyone?

in that time interval, the rhino traveled in the x direction a distance of -4.2m/s x 14.5s = -60.9m
in the y direction, the rhino traveled 4.5m/s x 14.5s = 65.3m
the x, y coordinate of the rhino are (-60.9, 65.3)
the distance from the origin is found from the Pythagorean theorem:
dist = Sqrt[(-60.9)^2 + 65.3^2] = 89.3m from the origin
in the y direction, the rhino traveled 4.5m/s x 14.5s = 65.3m
the x, y coordinate of the rhino are (-60.9, 65.3)
the distance from the origin is found from the Pythagorean theorem:
dist = Sqrt[(-60.9)^2 + 65.3^2] = 89.3m from the origin
