Calculate the average velocity of the cart for each fan mass. Round your answers to the nearest tenth. The cart with Low fan mass has an average velocity of cm/s.

The cart with Medium fan mass has an average velocity of cm/s.

The cart with High fan mass has an average velocity of cm/s.

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. 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;

The average velocity for the 2 kg fan mass, which is the cart with low fan mass, is = 500 cm/7.9 s ≈ 63.29 cm/s

The cart with low fan mass has an average velocity ≈ 63.29 cm/s

Part B

The average velocity of the cart with medium fan mass, 4 kg, is = 500 cm/11.1 s = 45. cm/s

The cart with medium fan mass has an average velocity ≈ 45. cm/s

Part C

The average velocity of the cart with high fan mass, 6 kg, is = 500 cm/13.7 s = 36.496 cm/s

The cart with high fan mass has an average velocity ≈ 36.496 cm/s.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
