Question

Complete the statements using data from Table A of your Student Guide. The speed of the cart after 8 seconds of Low fan speed is cm/s. The speed of the cart after 3 seconds of Medium fan speed is cm/s. The speed of the cart after 6 seconds of High fan speed is cm/s.

Answer 1

Answer:

8 seconds = 72cm

3 seconds = 36cm

6 seconds = 96cm

Explanation:

lab assignment i just took.

Answer 2

Speed is the rate of distance over time. The speed of the cart is as follows:

• $72cms^{-1}$ at 8 seconds.
• $36cms^{-1}$ at 3 seconds.
• $96cms^{-1}$ at 6 seconds.

Let:

$s \to$ speed

$d \to$ distance

$t \to$ time

After 8 seconds

For low fan speed; the distance (d) at 8 seconds is:

$d =576cm$

Speed (s) is calculated using:

$s = \frac dt$

$s = \frac{576cm}{8s}$

$s = 72cms^{-1}$

Hence, the speed after 8 seconds is $72cms^{-1}$

After 3 seconds

For medium fan speed; the distance (d) at 3 seconds is:

$d = 108cm$

The speed (s) is :

$s = \frac dt$

$s = \frac{108cm}{3s}$

$s = 36cms^{-1}$

Hence, the speed after 3 seconds is $36cms^{-1}$

After 6 seconds

For high fan speed; the distance (d) at 6 seconds is:

$d = 108cm$

The speed (s) is :

$s = \frac dt$

$s = \frac{576cm}{6s}$

$s = 96cms^{-1}$

Hence, the speed at 6 seconds is $96cms^{-1}$
