6. A boat travels for 2.0 hours at a constant velocity of 5.0 m/sec. How far does the boat travel? (1 hr = 3,600 sec)
305.8 meters
motion must always occur in a straight line, and the acceleration of the object must be constant.
12,755.1 meters
36,000 meters
Since sir resistance is large, it would be hard for things to free fall. The terminal velocity would be lower.
Air resistance reduces the acceleration of objects that are falling.
4,500 meters
when the ball returns to the place it was thrown, it has opposite velocity. Thus, its velocity is -1.2 m/sec (or down)
A ball is thrown up in the air with an initial velocity of 1.2 m/sec. If the ball is caught at exactly the same height from which it was thrown, what will its velocity be?

7. To measure the height of a building without a ruler or tape measure, an engineer drops a rock off the top of the building and finds out that it takes 7.9 seconds for the rock to reach the ground. How high is the building?

2. If the air were to be “thicker” would you expect the terminal velocity of the objects you are studying to be lower, higher, or the same as without fog?
