Question

3. What is the acceleration of a car at rest that stays at rest over 10 seconds?

a. 0.0 m/s2
b. 10 mph/s
C.-10 mph/s
d. 10 m/s2
e. Not enough data is given.

Answer 1

a.

Step-by-step explanation:

Use accleration formula,

`a = (v _(f) - v _(i))/(t)`

The initial velocity and final velocity is at zero. and t=10

So we got

`(0)/(10) = 0`

so

`a = 0`

a is the answer
