A ball rolls off a table 0.784 m high. With g = 9.8 m/s² and no air, how long does it take to land, Ari?
A ball rolls off a table 1.225 m high. With g = 9.8 m/s² and no air, how long does it take to land, Bo?
A ball rolls off a table 0.441 m high. With g = 9.8 m/s² and no air, how long does it take to land, Esme?

Trajectory grid (computed values, g = 9.8 m/s²)
Distance from the table (m) across, 0 to 1.6, a mark every 0.2 m; drop below the table top (m) down, 0 to 1.4, a mark every 0.2 m. The ball leaves the table edge at 3 m/s. Points every 0.1 s: (0 m, 0 m), (0.3 m, 0.049 m), (0.6 m, 0.196 m), (0.9 m, 0.441 m), (1.2 m, 0.784 m), (1.5 m, 1.225 m). At each point a horizontal arrow shows 3 m/s, and a downward arrow shows 0, 0.98, 1.96, 2.94, 3.92, 4.9 m/s.
In the trajectory grid, how long after leaving the table does the ball land, Jun?
- 1.225 s
- 0.5 s
- 1.5 s
- 0.25 s
In the trajectory grid, how far from the table does the ball land, Kira?
- 3 m
- 1.225 m
- 1.5 m
- 0.3 m
In the trajectory grid, how fast is the ball moving downward as it lands, Luz?
- 3 m/s
- 4.9 m/s
- 9.8 m/s
- 0 m/s
Two balls roll off the same table at 1 m/s and 3 m/s. How do their landings compare, Milo?
- Same time; the faster lands farther
- The faster one lands sooner
- The faster one lands later
- Same place, same time
Pia doubles the speed of a ball rolling off the same table. What happens to the landing distance?
- It becomes four times as far
- It halves
- It stays the same
- It doubles
The same ball lands moving 3 m/s sideways and 4 m/s down. About what angle below the horizontal is it moving, Tala?
- About 37°
- 90°
- About 45°
- About 53°
A ball leaves a table at 3 m/s. With no air, what is its sideways speed as it lands, Zee?
- 4.9 m/s
- 0 m/s
- 1.5 m/s
- 3 m/s
