Homework Statement
[/B]
A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t)=bt2−ct3, where b = 3.00 m/s2 and c = 0.130 m/s3 .
Calculate the average velocity of the car for the time interval t= 0 to t= 10.0 s
Homework Equations
[/B]
vav = V2-V1/T2-T1
The Attempt at a Solution
[/B]
x(t) = 3.00 t^2 - .130 t^3
differentiation \/
v(t) = 6.00t - .39 t^2
a(t) = 6.00 - .78t
V(0) = 6.00 (0) - .39 (0)
v(10) = 6.00 (10) - .39 (10)^2
= 60.0 - 39.
= 21
21-0/ 10-0
21/10

it tells me its wrong, why?
