Answer:
-0.8 m/s^2
Step-by-step explanation:
Acceleration is the slope of the velocity curve. Here the velocity decreases from 12 m/s to zero in 15 seconds. So, the slope is ...
(-12 m/s)/(15 s) = -0.8 m/s^2
Answer:
$45
Step-by-step explanation:
I think the point (4,60) represent the velocity
as the velocity at this point = distance / time
so v= 15 km/h
$31.85
$49 multiply by .35 = 17.15
$49-17.15 = $31.85
