Ayuda plisss, es urgente

(Lo siento si mi español es malo, no es mi primera lengua )

1. velocidad media = desplazamiento/tiempo

desplazamiento = 0 porque el athelete vuelve al punto inicial en un círculo

velocidad media = desplazamiento/tiempo = 0/10 = 0

2. la distancia entre A y B es 5 cm porque

a^2 + b^2 = c^2 (el teorema de Pitágoras) así:

rapidez media = distancia/tiempo = 5/5 = 1 cm/s o 0.01 m/s

y yo no se cómo hacer 3-5 :( lo siento

3. Creo que es dos triángulo s AB y CD menos la línea de fondo

5. Creo que es E + F porque B y D b y d cancelarse el uno al otro y C y C tambien pero no lo sé con seguridad.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
