Question

A car advertisement states that a certain car car that Emily miller love can accelerate from rest to 70km/h in 7 seconds.what’s the car average acceleration

Answer 1

The average acceleration of the car is 2.77 m/s².

Step-by-step explanation:

The average acceleration of a car can be calculated using the formula:

average acceleration = change in velocity / time

In this case, the car accelerates from rest (0 km/h) to 70 km/h in 7 seconds. The change in velocity is 70 km/h - 0 km/h = 70 km/h. Converting this to m/s, we get:

70 km/h * (1000 m / 1 km) * (1 h / 3600 s) = 19.4 m/s

So, the average acceleration of the car is:

average acceleration = 19.4 m/s / 7 s = 2.77 m/s²
