Acceleration Calculation Challenge

What is the formula to calculate acceleration based on the given data?

A car has uniformly accelerated from rest to a speed of 25 m/s after traveling. What is its acceleration?

A. a = Δv/t

B. a = v/f

C. a = t/Δv

Answer:

The acceleration of the car can be calculated using the formula a = Δv/Δt, where Δv is the change in velocity and Δt is the time it took for the change.

Explanation:

To find the acceleration of the car, we need to use the formula a = Δv/Δt, where Δv is the change in velocity and Δt is the time it took for that change to occur.

However, in this case, the question only provides the change in velocity (from 0 m/s to 25 m/s) but does not give us the time it took for this change to happen. Without the time information, we cannot definitively calculate the acceleration of the car.

Acceleration is defined as the change in velocity over the change in time. If we had the time value, we could plug it into the formula to find the acceleration value. For example, if the car took 5 seconds to reach 25 m/s, the acceleration would be 5 m/s². If it took 10 seconds, the acceleration would be 2.5 m/s².

Therefore, without knowing the time, we cannot accurately determine the car's acceleration based on the given data.
