First name: Last name: Question Title While jetting around in space, propelled by your jet pack, you come across an abandoned (powerless) rocket sled with that is moving to the right. You are able to exert a force on the sled in either direction. Choose the one force (A through G) which would keep the sled moving as described in each statement below. Answer choice J if you think that none is correct. Question Title * 2. Which force would keep the sled moving toward the right and speeding up at a steady rate (constant acceleration)? A B C D E F G J Question Title * 3. Which force would keep the sled moving toward the right at a steady (constant) velocity? A B C D E F G J Question Title * 4. Which force would slow the sled at a constant rate (constant acceleration) as it moves to the right? A B C D E F G J Question Title Use this figure for the following questions. Question Title * 5. The sled is pulled up a steeper hill of the same height as the hill described above. How will the velocity of the sled at the bottom of the hill (after it has slid down) compare to that of the sled at the bottom of the original hill? Choose the best answer below. The speed at the bottom is greater for the steeper hill. The speed at the bottom is the same for both hills. The speed at the bottom is greater for the original hill because the sled travels further. There is not enough information given to say which speed at the bottom is faster. None of these descriptions is correct. Question Title * 6. The sled is pulled up a higher hill that is less steep than the original hill described above. How does the speed of the sled at the bottom of the hill (after it has slid down) compare to that of the sled at the bottom of the original hill? The speed at the bottom is greater for the higher but less steep hill than for the original. The speed at the bottom is the same for both hills. The speed at the bottom is greater for the original hill. There is not enough information given to say which speed at the bottom is faster. None of these descriptions is correct. Done
