Answer:
Part A
The cart with low fan mass has an average velocity of approximately 63.29 cm/s
Part B
The cart with medium fan mass has an average velocity of approximately 45.[tex]\overline{045}[/tex] cm/s
Part C
The cart with high fan mass has an average velocity of approximately 36.496 cm/s
Explanation:
Part A
The average velocity is given as follows;
[tex]Average \ velocity, v_{average} = \dfrac{Total \ distance}{Elapsed \time \ to \ finish \ line} = \dfrac{\Delta x}{\Delta t}[/tex]
The average velocity for the 2 kg fan mass, which is the cart with low fan mass, is [tex]v_{average}[/tex] = 500 cm/7.9 s ≈ 63.29 cm/s
The cart with low fan mass has an average velocity [tex]v_{average}[/tex] ≈ 63.29 cm/s
Part B
The average velocity of the cart with medium fan mass, 4 kg, is [tex]v_{average}[/tex] = 500 cm/11.1 s = 45.[tex]\overline{045}[/tex] cm/s
The cart with medium fan mass has an average velocity [tex]v_{average}[/tex] ≈ 45.[tex]\overline{045}[/tex] cm/s
Part C
The average velocity of the cart with high fan mass, 6 kg, is [tex]v_{average}[/tex] = 500 cm/13.7 s = 36.496 cm/s
The cart with high fan mass has an average velocity [tex]v_{average}[/tex] ≈ 36.496 cm/s.
