Answer:
a) , b)
Explanation:
a) The acceleration due to gravity inside the planet is:
b) The acceleration at the surface of the planet is:
If the average velocity of the duck is zero, it means that the duck's location at the end of the time interval was the same as at the beginning of the interval, but says nothing about the duck's motion during that time.
For instance, the duck could have waddled around in a circle 20 times; as long as it wound up at the starting point, the displacement and average velocity is zero.
Answer:
1.
2.
3.
Explanation:
The velocity vector is
1. The position vector can be found by integrating the velocity vector.
At t = 0, the bird is at the origin, so the integration constants can be determined.
Therefore, C1 and C2 are equal to zero.
2. The acceleration vector is the derivative of the velocity vector with respect to time.
3. We will first find the time when the x-component of the position vector is equal to zero.
We will plug in this value into the y-component of the position vector.
Answer: 50 Pa
Explanation:
Pressure = Force/Area
Pressure = N/m^2
Pressure = 1250/25
Pressure = 50
Pressure = 50 Pa
