3. You are operating a remote-controlled model car on a vacant tennis court. Your position is the origin of coordinates, and the surface of the court lies in the xy-plane. The car, which we represent as a point, has x- and y- coordinates that vary with time according to x = 2.0 m – (0.25m/s²)r² y = (1.0 m/s)t + (0.025 m/s³)t³ a) Find the car's coordinates and its distance from you at timet=2.0 s. b) Find the car's displacement and average velocity vectors during the interval from t- 0s to t - 2.0 s. c) Find the components of the average acceleration in the interval from t = 0 s to t= 2.0 s.

solve for letter b please ASAP. if you can also solve for letter a.

 

3. You are operating a remote-controlled model car on a vacant tennis court. Your position is
the origin of coordinates, and the surface of the court lies in the xy-plane. The car, which
we represent as a point, has x- and y- coordinates that vary with time according to
x = 2.0 m – (0.25 m/s²)r² y = (1.0 m/s)t + (0.025 m/s')t³
a) Find the car's coordinates and its distance from you at time t = 2.0 s.
b) Find the car's displacement and average velocity vectors during the interval from
t = 0 s to t = 2.0 s.
c) Find the components of the average acceleration in the interval from t = 0 s to
t= 2.0 s.
