The following physics responses are provided by a student and, as such, should be considered in that context. While every effort is made for accuracy, absolute correctness cannot be fully guaranteed.
| C | I | Question | Answer |
|---|---|---|---|
| 1 | Which one of the choices below represents the preferred practice regarding significant figures when adding the following: 12.4 + 11 + 67.37 + 4.201? | 95 | |
| 1 | Which one of the choices below represents the preferred practice regarding significant figures when multiplying the following: 10.5 * 8.8 * 3.14? | 290 | |
| 1 | Which point is nearest the x axis? 1) (-3, 4) 2) (4, 5) 3) (-5, 3) 4) (5, -2) 5) (-4, 4) | (5, -2) | |
| 2 | A 50-g ball traveling at 25.0 m/s is bounced off a brick wall and rebounds at 22.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.50 ms, what is the average acceleration of the ball during this time interval? | 13400 m/s2 | |
| 2 | A ball is pushed with an initial velocity of 4.0 m/s. The ball rolls down a hill with a constant acceleration of 1.6 m/s^2. The ball reaches the bottom of the hill in 8.0 s. What is the ball's velocity at the bottom of the hill? | 17 m/s | |
| 2 | A ball is thrown vertically upwards at 19.6 m/s. For its complete trip (up and back down to the starting position), its average speed is: | 9.80 m/s. | |
| 2 | A ball is thrown vertically upwards at 19.6 m/s. For its complete trip (up and back down to the starting position), its average velocity is: | not given. | |
| 2 | A baseball catcher throws a ball vertically upward and catches it in the same spot when it returns to his mitt. At what point in the ball's path does it experience zero velocity and non-zero acceleration at the same time? | at the top of its trajectory | |
| 2 | A baseball is released at rest from the top of the Washington Monument. It hits the ground after falling for 6.0 s. What was the height from which the ball was dropped? (g = 9.8 m/s^2 and assume air resistance is negligible) | 1.8*10^2 m | |
| 2 | A basketball player can jump 1.6 m off the hardwood floor. With what upward velocity did he leave the floor? | 5.6 m/s | |
| 2 | A bird, accelerating from rest at a constant rate, experiences a displacement of 28 m in 11 s. What is its acceleration? | 0.46 m/s^2 | |
| 2 | A bird, accelerating from rest at a constant rate, experiences a displacement of 28 m in 11 s. What is the average velocity? | 2.5 m/s | |
| 2 | A bird, accelerating from rest at a constant rate, experiences a displacement of 28 m in 11 s. What is the final velocity after 11 s? | 5.1 m/s | |
| 2 | A cart is given an initial velocity of 5.0 m/s and experiences a constant acceleration of 2.0 m/s2. What is the magnitude of the cart's displacement during the first 6.0 s of its motion? | 66 m | |
| 2 | A Cessna aircraft has a lift-off speed of 120 km/hr. What minimum constant acceleration does this require if the aircraft is to be airborne after a take-off run of 240 m? | 2.31 m/s^2 |
