Answer:
Dy = - 0.0789 [m]
Explanation:
The vertical component of the vector can be determined with the sine of the angle.
Dy = 0.250*sin(18.4)
Dy = 0.0789 [m]
As the y-component is pointing downwards the component is negative.
Dy = - 0.0789 [m]
1. Make an observation
2. Form a question
3. Form a hypothesis
4. Conduct an experiment
5. Analyze the data and draw your conclusion
Answer:
- apples falling from trees
- people's feet touching the ground
- sky divers moving toward the ground
- balls bending downward after being thrown
Explanation:
When a space ship is accelerating in space, there is a force known as Inertia that kicks in. Inertia will mirror the effects of gravity on the ship even if there is no gravitational field effect such that anything that would happen where there is gravity, would continue to happen.
This means that apples will fall from trees, people's feet will touch the ground, sky divers will be pulled downwards and balls will bend downwards when thrown as well. These are the same effects expected on earth where gravity pulls things towards the earth's core.
Explanation:
We'll call the radius r and the diameter d:
We also assume that the riders are at a distance r = d/2 = 7m from the center of the wheel.
The period of the wheel is 24s. The tangent velocity of the wheel (and the riders) will be: (2pi/T)*r = 0.8 m/s (circa).
It means that in 3 minutes (180 seconds) they'll run 0.8 m/s * 180s = 144m.
Hopefully I understood the question. If yes, that's the answer.
