A ball rolls off a table 1.225 m high at 3 m/s. With g = 9.8 m/s² and no air, how far from the table does it land, Bo?
A ball rolls off a table 0.441 m high at 4 m/s. With g = 9.8 m/s² and no air, how far from the table does it land, Esme?
A drone flying forward at 4 m/s, 19.6 m above the ground, drops a ball. With no air, how long does the ball take to land, Jun?
- 19.6 s
- 2 s
- 0.5 s
- 4 s
How far forward of the drop point does that ball land, Kira?
- 8 m
- 0 m; it falls straight down
- 19.6 m
- 4 m
If the drone keeps flying at 4 m/s, where is it when the ball lands, Luz?
- Back at the drop point
- Behind the ball
- Directly above the ball
- 8 m ahead of the ball
Milo says a ball rolled off a table faster stays in the air longer. Agree or disagree?
- Disagree: the height alone sets the fall time
- Agree: a forward force holds it up
- Agree: faster balls stay up longer
- Agree: its sideways speed fades
Noah says a forward force keeps a ball moving after it leaves the table. Agree or disagree?
- Disagree: it keeps moving with no forward force
- Agree: it goes straight out, then drops
- Agree: faster balls fall slower
- Agree: without it the ball would stop
Pia says a ball's sideways speed stays the same after it leaves a table, with no air. Agree or disagree?
- Disagree: it slows as it falls
- Disagree: it goes straight out first, then drops
- Agree: no sideways force acts
- Disagree: a forward force fades
Water leaves a level hose at 5 m/s from 0.441 m above a bucket line. With no air, how far does it reach, Tala?
- 0.3 m
- 5 m
- 2.2 m
- 1.5 m
To make a ball land twice as far from the same table, what should Zee do?
- Double the table's height
- Double the launch speed
- Halve the launch speed
- Use a heavier ball
