Acar is going south on i-69 at 33 m/s (74 mph). the car has good brakes so its maximum braking acceleration is – 8.5 m/s^2 . traffic has come to a stop in all lanes 120 m ahead. what is the maximum reaction time the driver can have and still be able to stop in the available distance? hint: during the driver’s reaction time, the car continues to have the initial velocity of 33 m/s.

1.69515 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

The distance between the traffic and the car after braking is 120-64.06 = 55.94 m

Time = Distance / Speed

The reaction time cannot be more than 1.69515 seconds

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
