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.

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
