Chapter 1, Problem 2P
A man rides a bike along a straight road for 5 min, then has a flat tire. He stops for 5 min to repair the flat, but then realizes he cannot fix it. He continues his journey by walking the rest of the way, which takes him another 10 min. Use the particle model to draw a motion diagram of the man for the entire motion described here. Number the dots in order, starting with zero.

I am doing a lab report for my physics class. The lab consists of throwing a ball upward and recording its movements. Please explain these next questions and how you got the answer. The graphs attached below are my data for the ball in the x and y direction.
From the velocity vs. time graph(s), determine the ball's acceleration independently for each component of the motion as a function of time. What is the ball's acceleration just after it is thrown and just before it is caught or lands? What is the magnitude of the ball’s acceleration at its highest point? Is this value reasonable?
A car from rest moves with a constant velocity of 60 km/h for 2 hours. The driver then decided to take a break for 1 hour then continue his journey for 3 hours with a speed of 30 km/h. After arriving to his destination, he then goes back where he came from with a speed of 30 km/h in 4 hours.
a. Construct a Position-time graph of the motion.
