separate sheet of paper.

PART 2. PROBLEM SOLVING. Solve for what is asked in the word problems. Show your
complete solution on a separate sheet of paper.
1. A car moving with an initial velocity of 40 m/s East has a constant acceleration of 8 m/s²
West. What will be its velocity after 10 seconds?
2. At a stop light, a truck travelling at 15 m/s passes a car as it starts from rest. The truck
travels at constant velocity and the car accelerates at 3 m/s². How much time does the car
take to catch up to the truck?
3. A car begins driving from a stationary position. It accelerates at 4 m/s² for 10 seconds,
then travels at a steady speed for another 10 seconds, all in the same direction. How
much distance has it covered since it started driving?
PART 3. SKETCH A GRAPH. Provide what is asked in the problem on a separate sheet of paper.
A rigid ball traveling in a straight line (the x-axis) hits a solid wall and suddenly rebounds during
a brief instant. The graph shows this ball’s velocity as a function of time. During the first 20.0 s of
its motion, find:
a) The total distance the ball moves and its displacement.
b) Sketch a graph of for this ball’s motion.
c) Is the graph shown really vertical at 5.00 s? Explain.
