The positions on a standing wave where the largest amplitudes occur.
What are antinodes?
200
Projectiles
What objects moves through the air or through space, acted only by gravity (and air resistance)?
300
100 times per second
What is the frequency in vibrations per second of a 100-Hz wave?
300
At the top of it's path
At what point in its path does a projectile have minimum speed?
400
Group has it.
Draw constructive interference and destructive interference in a transverse wave?
400
Vertical acceleration is gravity. Horizontal accretion is zero (because no horizontal force acting on it).
A projectile is launched at an angle into the air. If there is air resistance, what is the vertical acceleration? Horizontal acceleration?
500
Neither. The frequency of a wave undergoes a change where there is motion of the source, not the was speed.
When a source moves toward you, do you measure an increase or decrease in wave speed?
500
Speed of the ball 20 m/s
A girl at a baseball game finds that ball and returned it to her team's player. She was 5 m up and the ball traveled20 m to the team player. What is the balls speed?
