Q1. At one instant a bicyclist is 41m due east of a park's flagpole, going due south with a speed of 14.0m/s. Then 33s later, the cyclist is 41m due north of the flagpole, going due east with a speed of 14.0m/s. For the cyclist in this 33.0 s interval, what are (a) magnitude and (b) direction of the displacement, (c) magnitude and (d) direction of the average velocity, and the (e) magnitude and (f) direction of the average acceleration? (Give all directions as positive angles relative to due east, where positive are measured going counter clockwise.)

Q2. A model rocket is launched straight upward with an initial speed of 47.8m/s. It accelerates with a constant upward acceleration of 2.07m/s2 until its engines stop at an altitude of 157 m. What is the maximum height reached by rocket?
