if a car can go from rest to 60 mph in 4.5 sec how long will it take the car to accelerate from rest to 30 mph?
Find the average acceleration
a = where
a = acceleration
Vf = final velocity
Vi = initial velocity
t = time
:
Initial V = 0, therefore
a =
a = 13.333 mph/sec^2
:
Find the time to accelerate to 30
t =
t = 2.25 sec
