Bill drives west at 20 —, then slows to a stop at the red light. A graph of his velocity over time is shown below, S where eastward is the positive velocity direction. Which graph shows his acceleration over time?​

divide the right side by the left side

0.024÷1.2=0.02 for example

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
