What are the three things that we graph over time?
Position, velocity and acceleration
100
True or False. The velocity in these problems is always the same.
True
100
True or False. The velocity in these problems is always the same.
False
200
True or False. The slope of the position vs time graph is equal to the velocity.
True

What is the starting velocity of an object at rest?
0 m/s

What would the sign of the acceleration be in this situation?
Negative

What is the acceleration of a runner starting from rest and finishing the race at 50 m/s in 5 minutes?
0.167 m/s2

A car is moving on a straight road. The car starts at position x = 10 m, and it moves during 15.0 seconds in the following way:
1) It starts from rest, and with a constant acceleration of 2.0 m/s2 for 5.0 seconds.
2) Then, the car stops accelerating, and continues moving with constant speed for 5.0 more seconds.
3) Finally, the car comes to a complete stop after 5.0 seconds (with constant acceleration).
Draw the velocity-vs-time graph of the car.

A car is moving on a straight road. The car starts at position x = 10 m and ends in position x = 235 m. It starts from rest, and with a constant acceleration of 2.0 m/s2 for 15.0 seconds. What is the final velocity?
30 m/s
