A ball rolls off a table 0.784 m high at 2.5 m/s. With g = 9.8 m/s² and no air, how far from the table does it land, Ari?
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
If the drone keeps flying at 4 m/s, where is it when the ball lands, Luz?
- Behind the ball
- 8 m ahead of the ball
- Directly above the ball
- Back at the drop point
Milo says a ball rolled off a table faster stays in the air longer. Agree or disagree?
- Agree: its sideways speed fades
- Agree: a forward force holds it up
- Agree: faster balls stay up longer
- Disagree: the height alone sets the fall time
Noah says a forward force keeps a ball moving after it leaves the table. Agree or disagree?
- Agree: it goes straight out, then drops
- Agree: without it the ball would stop
- Disagree: it keeps moving with no forward force
- Agree: faster balls fall slower
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
- Agree: no sideways force acts
- Disagree: a forward force fades
- Disagree: it goes straight out first, then drops
A ball must land 1.0 m from a table 0.784 m high. With no air, what speed should it leave at, Ren?
- 2.5 m/s
- 1.0 m/s
- 6.25 m/s
- 0.4 m/s
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
- 2.2 m
- 5 m
- 1.5 m
