A test driver’s perception-reaction time is being conducted on a special testing track with wet pavement and a driving speed of 50 kph. When the driver is sober, a stop can be made just in time to avoid hitting the object that is visible 40m. ahead. After a few drinks of San Miguel beer, under exactly the same condition, the driver fails to stop in time and strikes the object at speed of 30 kph. Determine the driver’s perception-reaction time after he was drinking. Assume coefficient of friction is 0.6

Question
A test driver’s perception-reaction time is being conducted on a special testing track with wet
pavement and a driving speed of 50 kph. When the driver is sober, a stop can be made just in time to
avoid hitting the object that is visible 40m. ahead. After a few drinks of San Miguel beer, under
exactly the same condition, the driver fails to stop in time and strikes the object at speed of 30 kph. Determine the driver’s perception-reaction time after he was drinking. Assume coefficient of friction
is 0.6
