2. 1D Motion / Kinematics Average Velocity
17PRACTICE PROBLEM
Mark starts his bike from his office at 5.30 p.m., moves at a constant speed towards the east for 5 minutes, takes a U-turn at 2800 m and drives at the same constant speed towards his house which is 4500 m from the U-turn. He reached his house at 5.50 p.m. Determine the average velocity of Mark's bike during these two intervals.
