Question

What is the average acceleration of an

automobile moving from 0 to 60 m/s in 3.0
seconds?
a. 90 m/s²
b. -20 m/s²
c. -90 m/s²
d. 20 m/s²

Answer 1

D

Step-by-step explanation:

Using the formula for average acceleration, which is:

average acceleration = (final velocity - initial velocity) / time

Where the initial velocity is 0 m/s and the final velocity is 60 m/s, and the time is 3 seconds, we get:

average acceleration = (60 m/s - 0 m/s) / 3 s = 20 m/s²

Therefore, the answer is (d) 20 m/s².
