A car advertisement states that a certain car can accelerate from rest to 70 km/h in 7 seconds. What is the car's average acceleration?
1 Answer
Explanation:
The acceleration of an object can be calculated based on the formula
where
a= "acceleration" v= "final velocity" u= "initial velocity" t= "time taken"
Here
From the question
u = "0 m/s" v= 19 4/9 \ "m/s" t = "7 s"
So
