10. A safe place to use the trebuchet would be away from other buildings and people. A good example of a place would be a large field with no nearby structures.
14. Many factors need to be kept consistent throughout the experiment. One example of a variable that would need to be consistent is the weight and size of the projectile.
15. It is important to do many trials so that you can make sure that the results of each trial are nearly the same. If they are all vastly different, then it means that something has gone wrong.
Sorry I was only able to answer a few questions, but I hope these few answers help! :)
Answer:
340cm = 3.4m
Explanation:
When converting units: cm to m, then you need to divide the cm by 100 to get its unit in m.
Acceleration =
(change of speed) / (time for the change).
Change of speed = (speed at the end) - (speed at the beginning)
= ( zero ) - (40 m/s)
= -40 m/s .
Acceleration = (-40 m/s) / (5 seconds)
= -8 m/s² .

Answer:
Explanation:
Una magnitud fundamental es aquella que se define por si misma y es independiente de las demás (masa, tiempo, longitud, etc.). magnitud derivada. Una magnitud derivada es aquella que se obtiene mediante expresiones matemáticas a partir de las magnitudes fundamentales (densidad, superficie, velocidad).
