Question

A car is stopped at a red light. When the light turns green, it accelerates up

to a velocity of 25 m/s over a period of 10 seconds. What is the
acceleration of the car?*

Answer 1

a = 2.5 [m/s²]

Step-by-step explanation:

To solve this problem we must use the following equation of kinematics.

`v_(f) =v_(o) +a*t`

where:

Vf = final velocity = 25 [m/s]

Vo = initial velocity = 0 (star from the rest)

a = acceleration [m/s²]

t = time = 10 [s]

25 = 0 + (a*10)

a = 25/10

a = 2.5 [m/s²]
