Projectile Motion: Horizontal Launch — Homework
Find the time of flight from the vertical drop FIRST, then use it for the horizontal part.
- 1.A ball rolls off a table 4.9 m high at a horizontal velocity of 10 m/s. Find the time of flight and the range.
- 2.A ball rolls off a cliff 78.4 m high at a horizontal velocity of 15 m/s. Find the time of flight and the range.
- 3.A marble rolls off a counter 2.0 m high at 3.0 m/s. Find the time of flight and the range (round to 2 sig figs).
- 4.Explain why doubling the horizontal launch speed doubles the range but does not change the time of flight.
- 5.Describe a real horizontal-launch scenario (a garden hose aimed level off a ledge, a toy car rolling off a table) and explain what you would need to measure to predict where it lands.
