Question

What acceleration does it take to reach 23.5 m/s (from rest) in 4.32 seconds?

19.2 m/s2

5.75 m/s2

5.44 m/s2

101.52 m/s2

Answer 1

it's the option c

Step-by-step explanation:

as we know a= vf- vi / t

it means change in velocity divided by time

at rest it's means 0 velocity it's our intial velocity

and 23.5 m/s is our final velocity as it stop their.

23.5 - 0/ 4.32 = 5.44 m/s

Hope it helps
