Question

What is the initial velocity in the problem below: "A car traveling initially at 7.0 m/s accelerates to velocity of 12.0 m/s in 2.0 s. What is the average acceleration of the car?

Answer 1

`a=2.5\ m/s^2`

Step-by-step explanation:

Given that,

Initial velocity, u = 7 m/s

Final velocity, v = 12 m/s

Time, t = 2 s

We need to find the average acceleration of the car. The acceleration of an object is equal to the rate of change of its velocity. It can be given by :

`a=(v-u)/(t)\\\\a=(12-7)/(2)\\\\a=2.5\ m/s^2`

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