1. While cruising along a dark sketch of highway at a speed of 25 m/s, you see that a bridge ahead has been washed out. You apply the brakes and uniformly slow down to a stop in 5.0 seconds.

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)

2. A poorly tuned Yugo can accelerate from rest to a speed of 28 m/s in 20 s.

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)

3. A bear is sitting at rest at t=0s. At t=5s, the bear notices honey 16 m away and takes off from rest accelerating at a rate of 2 m/s2 for 4 seconds to reach the honey.

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)

4. A dog runs down his driveway with an initial velocity of -5 m/s for 8 seconds, then uniformly increases his speed to -10 m/s in 5 seconds.

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)

5. You are driving on the highway at a rate of 40 m/s for 10 seconds when you notice a cop in front of you. Over the next 5 seconds you uniformly slow down to 35 m/s to avoid getting a speeding ticket.

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)

6. You are traveling 20 m/s when the stoplight in front of you turns red. You step on your break to uniformly slow down to a rest in 5 seconds. You are stopped at the red light for 3 seconds when the light turns green. You speed back up to 20 m/s over the next 5 seconds.

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)

The velocity values are ________. (Positive/Negative)

The acceleration value is _______. (Positive/Negative)

Therefore the object must be _________. (Speeding Up/Slowing Down)
