A rhinoceros is at the origin of coordinates at time t1=0. For the time interval from t1 to t2 = 13.0 s , the rhino's average velocity has x-component -3.2 m/s and y-component 6.0 m/s . At time t2= 13.0 s what is the x-coordinate of the rhino? At time t2= 13.0 s what is the y-coordinate of the rhino? How far is the rhino from the origin?

I'm trying to model the velocity over time of a given time interval in python, but my code won't work. I need to solve the problem using the Euler method. import numpy as np from matplotlib import pyplot as plt def car(x0, v0, Cd, p, A, m, facc, T, dt): n = 0 t = np.arange(0, T, dt) x = np.array([x0]) v = np.array([v0]) while x[n] > 0: x = np.append(x, x[n]+v[n]*dt) v = np.append(v, v[n]+(facc/m-(1/(2*m))*Cd*A*p*v[n])*dt) t = np.append(t, t[n]+dt)...

Here is the task:
You are tracking the velocity and position of a rocket-propelled
object near the surface of Mars. The velocity is v(t) and the
position is s(t), where t is measured in seconds, s in meters, and
v in meters per second. It is known that the v(t) = ds/dt = 4.94 –
3.72t and s(0) = 5.
A. Explain why the condition “f is continuous over [a, b]” from
the Evaluation Theorem is fulfilled by this scenario....

Learning Goal: To learn to read a graph of position versus time and to calculate average velocityIn this problem you will determine the average velocity of a moving object from the graph of its position z(t) as a function of time t. A traveling object might move at different speeds and in different directions durina an Now find vave [0,3].Find the average velocity over the time interval from 3 to 6 seconds
