Question

What is the acceleration of a car moving at a constant rate of 32.0 m/s for 3 seconds?

A) 0 m/s²
B) 32.0 m/s²
C) 96.0 m/s²
D) 10.67 m/s²

Answer 1

The acceleration of the car is 10.67 m/s².

Step-by-step explanation:

The acceleration of a car moving at a constant rate of 32.0 m/s for 3 seconds can be found using the formula:

Acceleration = (final velocity - initial velocity) / time

Given that the initial velocity is 0 m/s (since the car starts from rest) and the final velocity is 32.0 m/s, the acceleration can be calculated as:

Acceleration = (32.0 m/s - 0 m/s) / 3 s = 10.67 m/s²

Therefore, the correct answer is D) 10.67 m/s².
