Question

SITUATIONAL ANALYSIS:
You are an expert who have been hired as
a witness in a court case involving an
automobile accident. The accident
involved car A of mass 1900kg which
crashed into stationary car B of mass
1100kg. The driver of car A applied his
brakes 15m before he crashed into car B.
After collision, car A slid 18m while car B
slid 30m. The coefficient of kinetic friction
between the locked wheels and the road
was measured to be 0.60. Is It correct that
the driver of car A was exceeding the
90km/h speed limit before applying the
brakes? Give details using the
graphic organizer below:
