A sailor on a ship sees a cannon on the shore fire a cannon ball horizontally at the ship. The cannon is on a cliff that is 550 m from the boat and 56 m tall. How long will the sailor have to get off the ship before the cannon ball hits if the initial velocity of the ball was 32 m/s?.

  1. A sailor on a ship sees a cannon on the shore fire a cannon ball horizontally at the ship. The cannon is on a cliff that is 550 m from the boat and 56 m tall. How long will the sailor have to get off the ship before the cannon ball hits if the initial velocity of the ball was 32 m/s?

  2. A golf ball rolls off a horizontal cliff with an initial speed of 11.4 m/s. The ball falls a vertical distance of 15.5 m into a lake below. (a) How much time does the ball spend in the air? (b) What is the speed of the ball just before it strikes the water?

  3. A golf ball is hit with a 52o wedge (type of golf club) at 21 m/s. How high will the ball get at its highest point and how far will the ball travel?

  4. A ball is thrown straight upward and returns to the thrower’s hand after 3.00 s in the air. A second ball is thrown at an angle of 30.0o with the horizontal. At what speed must the second ball be thrown so that it reaches the same height as the one thrown vertically?

  5. During a thunderstorm, a tornado lifts a car to a height of 125 m above the ground. Increasing in strength, the tornado flings the car horizontally with an initial speed of 90.0 m/s. How long does the car take to reach the ground? How far horizontally does the car travel before hitting the ground?

  6. A red Cross plane drops a food package of emergency rations to a stranded party of explorers. The plane is traveling horizontally at 100.0 m/s at a height of 50.0 m above the ground. What horpzontal distance does the package travel before striking the ground?

  7. The 1994 Winter Olympics included the aerials competition in skiing. In this event skiers speed down a ramp that slopes sharply upward at the end. The sharp upward slope launches them into the air, where they perform acrobatic maneuvers. In the women’s competition, the end of a typical launch ramp is directed 63o above the horizontal. With this launch angle, a skier attains a height of 13 m above the end of the ramp. What is the skier’s launch speed?

  8. A cat chases a mouse across a 1.0 m high table. The mouse steps out of the way, and the cat slides off the table and strikes the floor 2.2 m from the edge of the table. What was the cat’s speed when it slid off the table?
