Short answer Parabolic Motion Questions like the multiple choice questions.

1. A ball rolls down a curved ramp as shown in the diagram below. Draw a line, from the bottom of the ramp that best represents the path of the ball after leaving the ramp?

2. Above the ground, an arrow A, is shot horizontally from a bow at a speed of 50 m/s, as shown in the diagram below. The second arrow, B, is dropped from the same height and at the same instant as A is shot.

B A

Neglecting air friction, compare the amount of time it takes A takes to strike the ground, to the amount of time it takes B takes to strike the ground.

3. The diagram below shows a projectile moving with speed v at the top of its trajectory.

V

Ground

Draw a vector that best represents the acceleration of the projectile in the position shown?

4. The diagram below shows a baseball being hit with a bat. Angle [pic] represents the angle between the horizontal and the ball’s ignition direction of motion

Baseball [pic]

Horizontal Line

Which value of [pic] would result in the ball traveling the longest horizontal distance?

5. A ball is projected horizontally to the right from a height of 50 meters as shown in the diagram below.

Draw a diagram that best represents the position of the ball at 1.0second intervals?

6. The diagram below shows the muzzle of a cannon located 50 meters above the ground. When the cannon is fired, a cannonball leaves the muzzle of the cannon with an initial velocity of 250 m/s.

50 m

What action can you take to increase the time of flight of the ball fired by the cannon?

7. A boy can stands on the edge of a cliff and throws a ball at 25 m/s horizontally off the cliff. You can choose from several cliffs to throw the baseball from. What height cliffs would give the boy the longest range?

8. In the diagram below a stationary observer on a life raft watches a coastguard plane flying horizontally with velocity “V” to the right drop a care package

V

Draw the path the care package would take as seen by the man in the life raft?

9. A Park View softball player hits a homerun while playing Stone Bridge. After the game she describes the homerun to her parents. What is the best word to describe the trajectory of the ball?

Ground

10. A Cannon is set on a hill that is 75 meters high. What can you do to enable the cannons will have the longest range?

Problems. Show ALL your work. Remember the 5 point method. Please write a table and fill it in.

1. A State Trooper investigating an accident came upon the following scene. A car had slid off an embankment that is 30 m high and landed 55 m into a field. Fortunately the driver survived and told the State Trooper that he wasn’t speeding when he lost control of his car. Help the State Trooper determine whether the man was speeding or not.

30 m

55 m

a. How long did it take the man to hit the ground?

b. If the posted speed limit was 20 m/s was the driver of the car speeding when the car left the top of the cliff? Prove your answer.

c. What is the final vertical velocity of the car the moment before it strikes the ground.

2. You stand on the top of a hill 50 m high and shoot an arrow at 20 m/s as shown.

50 m

? m

a. How long does it take the arrow to reach the ground?

b. How far away from the base of the cliff will the arrow land?
