A college student named Nova walked 500 meters for 500 seconds from her dormitory building to find her favorite
bench in a park. She called her mom and talked for 100 seconds at the bench, but suddenly she remembered that she
did not turn off the gas stove. So, she returned her dorm by running for 100 seconds. To find out Nova's average
velocity for each case while walking, resting, and running, begin by plotting a graph between position and time. Please
be aware that the walking mode is a positive direction and the running mode is a negative direction of Nova's motion.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
