QuestionAnswer
A bird, accelerating at a constant rate, experiences a displacement of 28 m in 11 s. What is the average velocity? 2.5 m/s
A railroad train travels forward along a straight track at 80.0 m/s for 1000 m and then travels at 50.0 m/s for the next 1000 m. What is the average velocity? 61.5 m/s
A European sports car dealer claims that his car will accelerate at a constant rate to 100 km/h in 8.00 s. If so,What is the acceleration. (Hint: First convert speed to m/s) 3.4 m/s^2
A ball is pushed with an initial velocity of 4.0 m/s. The ball rolls down a hill with a constant acceleration 1.6 m/s^2. The ball reaches the bottom of the hill in 8.0 s. What is the balls velocity at the bottom of the hill?

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
