Osama was testing his new car by racing with his fiend Adam, Osama was driving at 54.0 mile/hr, enters a one-way narrow subway. Osama then observed a Truck 100 m ahead traveling at a low constant speed 3.00 m/s. Osama used his brakes but can accelerate only at -2.00 m/s2 because the road was wet. Will there be an accident? Explain. If yes, Page 5 of 8 5 at what time the accident occurs and how far into the subway. If no, determine the distance of closest approach between Osama’s car and the Truck. (1mile=1609m).
