  1. A 5 m long bridge was washed out by a rain storm. How fast must a car be traveling to successfully jump the stream? The road on the opposite side of the bridge is 2m lower. 5 m/s 7.5 m/s 8 m/s 10 m/s

  2. 2. A batter hits a pop-fly ball in to the air. The maximum height the ball will reach may be described by which of the following? A. -9.8(v) B. -V2 / 2a C. -(v sin Θ)2 / 2a D. -(v sin Θ)2 / a E. -(v sin Θ) / a

  3. 3. Two cannons are fired at the same angle. The initial speed of cannonball B is twice the speed of cannonball A. The horizontal distance of B is: DB = DA DB = 2 DA DB = (sq rt2) DA DB = 4 DA Cannot be determined

  4. 4. A hunter shoots at a horizontally flying duck which was H meters high. The time interval between when the duck was shot, and when it fell to the ground depends on A. how fast the duck was flying. B. how fast the duck was flying and the height, H. C. just the height, H. D. the height, H, and the distance between the duck and the shooter.

  5. A stone is thrown from the top of a tall cliff with a speed of 10 m/s straight down. If the stone were thrown straight upwards with the same speed from the same position, it would end up hitting the ground with The same speed Less speed More speed

  6. Two vectors, of magnitudes 50 and 100 cm, may be added together to sum to any of the following except: 75 cm 100 cm 150 cm 175 cm E. None of these

  7. It has been alleged that George Washington threw a coin across a river. Assuming the coin was thrown at a 45 degree angle, and the river was 62.5 m wide, find the time the coin was in the air. A. Cannot be determined B. 1.75 seconds C. 3.5 seconds D. 4.0 seconds E. 7.0 seconds

  8. 8. Which of the following is NOT a VECTOR? A. time B. velocity C. acceleration D. displacement E. None of these

  9. 9. A boat wishes to travel at a velocity of 10 m/s directly southwest, but the river’s current runs at a speed of 4 m/s east. Find the speed the boat must travel to accomplish its’ desired velocity A. 7.75 m/s B. 8.0 m/s C. 12.0 m/s D. None of these
