Question

What is the acceleration of an object if it goes from a velocity of +25 m/s to rest in 5.0 s?

A.) –5 m/s^2
B.) +5 m/s^2
C.) –25 m/s^2
D.) +25 m/s^2

Answer 1

It's A

Step-by-step explanation:

Answer 2

The answer is A.) -5 m/s^2

The formula is as follows:

a = (final velocity - initial velocity) / (final time - initial time)
a = (-25 m/s)/ 5 s
a = -5 m/s^2
