An object is moving initially with a velocity of 5.6 m/s. After 3.1 s the object's velocity is -2.7 m/s. What is the object's average acceleration during this time

Answer:

-2.68m/s²

Explanation:

To find acceleration use the formula:

acceleration = change in velocity ÷ time

  • change in velocity = -2.7 - 5.6 = -8.3m/s (final velocity - initial velocity)
  • time = 3.1s

Substitute in the values:

acceleration = -8.3 ÷ 3.1

acceleration = -2.67741.. ≈ -2.68m/s²

Hope this helps!
