  2. Seed Question Six rocks with different masses are thrown straight upward from the same height at the initial velocities shown next to each diagram. Rank the rocks on the basis of their maximum heights from the greatest to the least height. Support your answer with complete sentences.

  3. Number 1 A cannon ball is shot upward at an angle. Describe the magnitude and direction of the forces acting on the ball and its acceleration horizontally and vertically as it is moving upward, at its highest point, and as it travels downward.

  4. 5 m/s 8 m/s 10 m/s 8 m/s 20 m/s F A E B C 40 cm 40 cm 40 cm 80 cm 80 cm 8 m/s D 60 cm Number 2 Now compare the distance the toy truck will travel in diagram C versus F. Explain your reasoning in at least 2 complete sentences. Now compare the distance the toy truck will travel in diagram B versus C. Explain your reasoning in at least 2 complete sentences. Six identical toy trucks are rolling along the tables shown below in the diagrams. The speed of the trucks are shown above each diagram and the height of the tables are shown to the left of the diagram. Rank the following trucks based on how long the trucks are in the air. 20 m/s 8 m/s and 80 cm 5 m/s and 80 cm 20 m/s 40 cm 8 m/s and 60 cm 10 m/s 40 cm 8 m/s 40 cm

  5. Number 3 Cathy Droll rolls a bowling ball off the roof of his school. If she rolls the ball at 19.7 m/s, it hits the ground 46.2 m horizontally from the edge of the roof. How high is the roof? How fast was the ball going when it hit the ground?

  6. Number 4 Jack B. Nimble shoots a rock with his slingshot horizontally at a wall 15.0 m away. It hits the wall in 40.s. • How fast was the rock traveling when it left the slingshot? • How far had it fallen when it hit the wall?

  7. Number 5 A ball is projected horizontally from the top of a 92.0-meter high cliff with an initial speed of 19.8 m/s. Determine: (a) the horizontal displacement (b) the final speed the instant prior to hitting the ground.

  8. Number 6 Determine the launch speed of a horizontally launched projectile that lands 26.3 meters from the base of a 19.3-meter high cliff.

  9. Number 7 A soccer ball is kicked horizontally at 15.8 m/s off the top of a field house and lands 33.9 metes from the base of the field house. Determine the height of the field house.

  10. Number 8 A pool ball leaves a 0.60-meter high table with an initial horizontal velocity of 2.4 m/s. Predict the time required for the pool ball to fall to the ground and the horizontal distance between the table's edge and the ball's landing location.

  11. Number 9 A soccer ball is kicked horizontally off a 22.0-meter high hill and lands a distance of 35.0 meters from the edge of the hill. Determine the initial horizontal velocity of the soccer ball.

  12. Number 10 Anita Break rolls a golf ball off of a 76 cm tall table with an initial velocity of 1.67 m/s. Determine the following: a) How long will it take the ball to reach the ground? b) How far from the table will the ball strike the ground? C) What fast will the ball be going vertically just before it hits the ground? What about horizontally?
