Question

A car accelerates at 5.6m/s^2 from rest to 24.0m/s. How long will it take to reach that speed??

Answer 1

4.29s

Step-by-step explanation:

Using Newton's equation:

Final velocity = initial velocity + (acceleration)(time)

From the question, we have

• acceleration = 5.6m/s^2
• initial velocity = 0m/s

• final velocity= 24m/s

Putting values,

24= 0 +(5.6)(t)

24/5.6=t

4.29s=t
