In the lab, you looked at speed-time graphs to determine the acceleration of the cart for each of the three fan speeds.
What was the acceleration of the cart with Low fan speed?
cm/s2
What was the acceleration of the cart with Medium fan speed? cm/s2
What was the acceleration of the cart with High fan speed?
cm/s2

18.0, 24.0, 32.0

Explanation:

just did it

(I).  The acceleration of the cart with low fan speed is 18 cm/s²

(II). The acceleration of the cart with medium fan speed is 23.3 cm/s²

(III).  The acceleration of the cart with high fan speed is 32 cm/s²

Explanation:

Given that,

You looked at speed-time graphs to determine the acceleration of the cart for each of the three fan  speeds in the lab.

According to graph,

A , B and shows the high, medium and low fan speeds respectively.

We know that,

The speed-time graph shows the acceleration.

Acceleration is equal to the rate of change of velocity.

(I). We need to calculate the acceleration of the cart with low fan speed

Using formula of acceleration

Put the value from graph

(II). We need to calculate the acceleration of the cart with medium fan speed

Using formula of acceleration

Put the value from graph

(III). We need to calculate the acceleration of the cart with high fan speed

Using formula of acceleration

Put the value from graph

Hence, (I).  The acceleration of the cart with low fan speed is 18 cm/s²

(II). The acceleration of the cart with medium fan speed is 23.3 cm/s²

(III).  The acceleration of the cart with high fan speed is 32 cm/s²

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
