Jim Guinn’s PHYS2211 Assignment #2 1. Starting at the initial position of +25m , Azadeh walks with a constant velocity of -3m/s . a) What is Azadeh’s position after 4sec? b) What is Azadeh’s position after 12sec? c) What is Azadeh’s velocity after 20sec? d) What is Azadeh’s acceleration after 25sec? 2. Seeing Azadeh out walking, starting from the origin Wakjira decides to go for a run with a velocity shown in the graph below. What is Wakjira’s position at t = 70.0s? 3. Seeing Azadeh and Wakjira outside, starting from the origin Anna decides to go for a run with a velocity shown in the graph below. What is Anna’s position at t = 70.0s? 4. Seeing so many people outside, starting from the origin Kenny decides to go for a run with
