A spring toy launches a ball from level ground with a horizontal part of 2 m/s and a vertical part of 12.25 m/s. With no air, how far away does it land, Ari?
In the trajectory grid, what are the ball's velocity parts at 1 s, Jun?
- 2.5 m/s across, 9.8 m/s down
- 0 across, 4.9 m/s up
- 2.5 m/s across, 14.7 m/s up
- 2.5 m/s across, 4.9 m/s up
In the trajectory grid, when is the ball at its highest point, Kira?
Use the picture in question 2.
- 3 s
- 2 s
- 1.5 s
- 1 s
In the trajectory grid, what is the vertical part of the velocity at 2.5 s, Luz?
Use the picture in question 2.
- 9.8 m/s upward
- 9.8 m/s downward
- 0 m/s
- 24.5 m/s downward
Milo says a launched ball is completely stopped at the top of its arc. Agree or disagree?
- Agree: both parts of its motion stop
- Agree: the whole flight takes the time to the top
- Disagree: it still moves sideways
- Agree: steeper launches go farther
Noah says the steeper the launch, the farther the ball lands. Agree or disagree?
- Agree: at the top it stops
- Disagree: 45° lands farthest
- Agree: a steeper launch lands farther
- Agree: the vertical part is v cos θ
Pia says a ball's whole flight takes twice as long as reaching the top, on level ground with no air. Agree or disagree?
- Disagree: the horizontal part is v sin θ
- Disagree: the flight equals the time to the top
- Disagree: steeper launches fall faster
- Agree: up and down take equal times
A ball with a horizontal part of 3 m/s must land 6 m away on level ground. What vertical part does it need, Ren?
- 4.9 m/s
- 19.6 m/s
- 2 m/s
- 9.8 m/s
To double a ball's time in the air, what should Tala double?
- The horizontal part of the launch
- The vertical part of the launch
- The ball's mass
- The range
A 45° launch on level ground has its speed doubled. With no air, what happens to its range, Zee?
- It stays the same
- It becomes 4 times as far
- It halves
- It doubles
