Examples:

1. A tennis ball is thrown horizontally from the top of a water tower and lands

20.0m from the base of the water tower. If the tennis ball is initially thrown

at a velocity of 10.0m/s, determine the height of the water tower?

2. A soccer player, running on a level playing field, kicks a soccer ball with a

velocity of 9.4 m/s at an angle of 40 above the horizontal. Determine the

soccer ball's maximum height and horizontal displacement. State the soccer

ball's final velocity before making contact with the ground.

3. As part of a physics investigation, a student launches a beanbag out of an

open window with a velocity of 4.5 m/s at an angle of 250 above the

horizontal. If the window is 12m above the ground, determine how far away

from the building must the student's friend stand to catch the beanbag at

ground level? Determine the final velocity of the bean bag just before it is

caught.

Practice:

4. An archer shoots at a target 60 m away. If she shoots at a velocity of 55m/s

[right] from a height of 1.5 m, does the arrow reach the target before striking

the ground? Provide numerical evidence to justify your answer What should

the archer do to get her next shot on target?

5. A superhero launches himself from the top of a building with a velocity of

7.3 m/s as an angle of 250 above the horizontal. If the building is 17 m high,

determine how far will he travel horizontally before reaching the ground?

Determine his final velocity.

[15 m, 20 ms"] 70 below the hor.]

6. A championship golfer uses a nine iron to chip a shot right into the cup. If

the golf ball is launched at a velocity of 20 ms" at an angle of 450 above the

horizontal, how far away was the golfer when he hit the ball? Determine the

maximum height the ball reached? [41m, 10m]
