This Section Test deals with the basic one-dimensional and two-dimensional kinematics problems. Questions regarding objects in free fall, vectors, and projectiles are covered.
1. A bowling ball is dropped from the top of a 200m high building. How long does it take the bowling ball to reach a speed of 98m/s (ignoring air resistance)?
2. Starting from rest, a marble rolls freely down an incline that is 10 m long in 2.0 s. The acceleration of the marble is?
3. A driver of a race car has their foot to the accelerator but then begins to release it half way, the car's ______________.
4. A student on a flat field throws a baseball 8√2 m/s at 45 degrees above the horizontal. How long does the ball remain in flight before it hits the ground (ignoring air resistance)?
5. A car traveling north at 10 m/s shifts into reverse and experiences a uniform acceleration of 4 m/s2 south. What is the final velocity of the car after 5 seconds?
6. A ball is thrown horizontally off a cliff at 4m/s and after 6 seconds hits the ground below. How far will the ball have traveled in the horizontal direction after 3 seconds? (Gravity is 9. m/s2)
7. A student standing on a bridge 32 m above the water drops a stone. After 5 seconds, the student throws a second stone straight down. What initial velocity must the second stone be given to ensure both stones hit the water below at the same time?
8. A cannon ball is fired off a ship at 35 degrees above the horizontal, ignoring air resistance, what happens to the magnitude of the velocity for the duration of the flight?
9. How long does it take a marble to hit the ground if it is dropped from the top of a building 200m high?
10. A sail boat at the center of a 4km wide river with a current of 5km/h south is pushed by the wind east at 10km/h. How far south, down the river from the bank, does the boat sail?
11. A soccer ball is kicked off a cliff that is 50m, at 45 degrees above horizon at a velocity of 5√2 m/s. What is the distance from the base of the cliff to the place the soccer ball lands?
