At one instant a bicyclist is 60 m due east of a park’s flagpole, going south at

20 m/s. Then 30 s later, the cyclist is 40 m due north of the flagpole, going due east with a speed of 10 m/s. On an XY- coordinate system with the flagpole at the origin, for the cyclist in this 30 s time interval

a) Draw the position and velocity vectors of the bicyclist as described.

b) On your graph in part (a) label the direction of the displacement vector,

average velocity vector, and average acceleration vector.

c) Calculate the displacement vector in unit-vector notation.

d) Calculate the average velocity vector in unit-vector notation.

e) Calculate the average acceleration vector in unit-vector notation.

    At one instant a bicyclist is 40.0m due east of a park's flagpole, going due south with a speed of 10.0m/s. Then 30.0s later, the cyclist is 40.0m due north of the flagpole, going due east with a speed of 10.0 m/s. For the cyclist in the 30.0s interval, what are the (a) magnitude and (b) direction of the displacement, the (c) magnitude and(d) direction of the average velocity and the (e) magnitude and (f) direction of the average acceleration?
