Question

Use the equation to answer the question.

v = v0 + at

A car company advertises that a certain model of car can go from 0 to 100 km/h in 4 seconds. What is the car’s acceleration?

400 km/hr/s

0.04 km/hr/s

25 km/hr/s

96 km/hr/s

Answer 1

100km/hr = 0 + 4 s * a

a =100/4 = 25 km/ hr s

Answer 2

anon is right! 25km/hr/s! bc 25x4 = 100 :)

Answer 3

[AI-generated answer — Step-by-Step Bot]

To find the acceleration, we need to rearrange the equation, v = v0 + at, and solve for "a". In this case, the initial velocity (v0) is 0 km/h since the car starts from rest. The final velocity (v) is 100 km/h, and the time (t) is 4 seconds.

Substituting these values into the equation, we have:

100 km/hr = 0 km/hr + a * 4 sec

Simplifying the equation, we get:

100 km/hr = 4a

To solve for "a", we divide both sides of the equation by 4:

100 km/hr ÷ 4 = 4a ÷ 4

25 km/hr = a

Therefore, the car's acceleration is 25 km/hr/s.

Answer 4

To find the car's acceleration, we need to use the equation v = v0 + at and make certain conversions.

Given: v0 = 0 km/h (initial velocity), v = 100 km/h (final velocity), and t = 4 seconds (time).

First, we need to convert the velocities from km/h to km/s, as we want the acceleration in km/h/s.

v0 = 0 km/h = 0 km/h * (1 hour/3600 seconds) = 0 km/s

v = 100 km/h = 100 km/h * (1 hour/3600 seconds) = (100/3600) km/s

Now, substitute these values into the equation:

v = v0 + at

(100/3600) km/s = 0 km/s + a * 4 seconds

To isolate 'a' (acceleration), we can multiply both sides of the equation by 4 seconds:

(100/3600) km/s * 4 seconds = a * 4 seconds * 4 seconds

Simplifying:

(400/3600) km = a * 16 seconds

Dividing both sides by 16 seconds:

(400/3600) km/16 s = a

a ≈ 0.044 km/hr/s

So, the car's acceleration is approximately 0.044 km/hr/s. Therefore, the nearest answer among the provided options is 0.04 km/hr/s.
