Question

A car accelerates uniformly from 5 m/s to 13 m/s in 4.0 s. What is the acceleration of the car in m/s²?

A) 2.0
B) 2.5
C) 3.0
D) 3.5

Answer 1

The acceleration of the car is 8.0 m/s².

Step-by-step explanation:

To find the acceleration of the car, we can use the formula:

acceleration = (final velocity - initial velocity) / time

Given that the initial velocity is 5 m/s, the final velocity is 13 m/s, and the time is 4.0 s, we can substitute these values into the formula.

acceleration = (13 m/s - 5 m/s) / 4.0 s = 8.0 m/s²

Therefore, the acceleration of the car is 8.0 m/s².
