Question

What is the acceleration of a car initially traveling at -5m/s and
reaching -22m/s in 3s.

Answer 1

`a=-5.67\ m/s^2`

Step-by-step explanation:

Given that,

Initial velocity, u = -5 m/s

Final velocity, v = -22 m/s

Time, t = 3s

We need to find the acceleration of the car. The formula of it is given by :

Acceleration,

`a=(v-u)/(t)\\\\a=((-22)-(-5))/(3)\\\\a=-5.67\ m/s^2`

So, the acceleration of the car is
`-5.67\ m/s^2`.
